How to Build

Setup an environment with the dependencies installed

Install dependencies on MAC (with xcode installed)

Make sure you have done: xcode-select --install to install developer tools

brew install protobuf protobuf-c Gsasl openssl boost thrift json-c ccache snappy libyaml libevent python cmake lcov apr
brew link openssl apr --force
 
brew install iproute2mac
 
brew cask install java
brew install maven
# need tomcat6 if enable-rps
brew install tomcat@6
 
sudo easy_install pip
sudo pip install pycrypto

brew install cpanm
sudo cpanm install JSON

#get libesmtp from http://linuxfromscratch.org/blfs/view/svn/general/libesmtp.html
tar jxvf libesmtp-1.0.6.tar.bz2
cd libesmtp-1.0.6
./configure && make
sudo make install

Please refer to section below titled Running catalog tidycat perl modules for installing perl-JSON module on MAC/

Note for Installing Dependencies

OS requirement

Use a text editor to edit the /etc/sysctl.conf file. Add or edit each of the following parameter definitions to set the required value. 

       kern.sysv.shmmax=2147483648

       kern.sysv.shmmin=1

        kern.sysv.shmmni=64

        kern.sysv.shmseg=16

        kern.sysv.shmall=524288

        kern.maxfiles=65535

        kern.maxfilesperproc=65536

  • Reboot to apply the change.

Install Xcode and command line tools

After install/update xcode, please run ‘xcode-select --install’ to install command line tools, and then open xcode to make sure you have already installed it. 

MUST: Turning Off Rootless System Integrity Protection in OS X El Capitan 10.11+

If not do this, you may encounter some tricky LIBRARY_PATH problems. e.g. HAWQ-513

Following below instructions: ( refer to http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x )

  1. Reboot the Mac and hold down Command + R keys simultaneously after you hear the startup chime, this will boot OS X into Recovery Mode
  2. When the “OS X Utilities” screen appears, pull down the ‘Utilities’ menu at the top of the screen instead, and choose “Terminal”
  3. Type the following command into the terminal then hit return: csrutil disable; reboot

Build dependencies yourself ( tested on Red Hat 6.X).

Dependencies

There are several dependencies (see the following table) you must install before building HAWQ. To build Apache HAWQ, gcc and some dependencies are needed. The libraries are tested on the given versions. Most of the dependencies can be installed through yum. Other dependencies should be installed through the source tarball. Typically you can use "./configure && make && make install" to install from source tarball.

Libraries that must be installed using source tarball.


 You might need to run "ldconfig -p <LIBRARY_INSTALL_PATH>" after installing them.

For thrift build, you might need "--without-tests" for configure.

Install maven:
sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven

Install pip:

wget https://bootstrap.pypa.io/get-pip.py

python get-pip.py

 

pip --retries=50 --timeout=300 install pycrypto

Default version of gcc in Red Hat/CentOS 6.X is 4.4.7 or lower, you can quickly upgrade gcc following instructions below:

cd /etc/yum.repos.d
# make sure you have root permission
wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
# install higher version using devtoolset-2
yum install devtoolset-2-gcc devtoolset-2-binutils devtoolset-2-gcc-c++
# Start using software collections
scl enable devtoolset-2 bash

You will need to install python packages same as those which are required for Red Hat/CentOS 7.

Build with Prebuilt Docker Image

Apache HAWQ source code contains the Dockerfiles to help developers to setup building and testing environment with docker.

To use the docker image follow the steps on: https://github.com/apache/incubator-hawq/tree/master/contrib/hawq-docker

Install Hadoop

Please follow the steps here: https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/SingleCluster.html

Note:

  • you might need to build hadoop from source on Red Hat/CentOS 6.x if the downloaded hadoop package has higher glibc version requirement. When that happens, you will probably see the warning below when running start-dfs.sh." WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform"
  • You will also need to set  the port for fs.defaultFS to 8020 in etc/hadoop/core-site.xml (The example above set it as 9000.)
  • HDFS is a must, but YARN is optional. YARN is only needed when you want to use YARN as the global resource manager.
  • must setup passphraseless ssh, otherwise there will be some problems of "hawq init cluster" in the following step.

Your need to verify your HDFS works.

# start HDFS
start-dfs.sh
 
# Do some basic tests to make sure HDFS works
echo "test data" >> ./localfile
hadoop fs -mkdir /test
hadoop fs -put ./localfile /test
hadoop fs -ls /
hadoop fs -get /test/localfile ./hdfsfile

Get the HAWQ code and Compile

Once you have an environment with the necessary dependencies installed and Hadoop is ready, the next step is to get the code and build HAWQ

# The Apache HAWQ source code can be obtained from the the following link: 
# Apache Repo: https://git-wip-us.apache.org/repos/asf/incubator-hawq.git or 
# GitHub Mirror: https://github.com/apache/incubator-hawq. 
git clone https://git-wip-us.apache.org/repos/asf/incubator-hawq.git
 
# The code directory is incubator-hawq.
CODE_BASE=`pwd`/incubator-hawq
 
cd $CODE_BASE
 
# Run command to generate makefile.
./configure

# Or you could use --prefix=/hawq/install/path to change the Apache HAWQ install path, 
# and you can also add some optional components using options (--with-python --with-perl)
# For El Capitan (Mac OS 10.11), you may need to do: export CPPFLAGS="-I/usr/local/include -L/usr/local/lib" if the configure cannot find some components
./configure --prefix=/hawq/install/path --with-python --with-perl

# If enable-rps
export CATALINA_HOME=/tomcat/install/path
./configure --prefix=/hawq/install/path --enable-rps

# You can also run the command with --help for more configuration.
./configure --help


# Run command to build and install
# To build concurrently , run make with -j option. For example, make -j8
# On Linux system without large memory, you will probably encounter errors like
# "Error occurred during initialization of VM" and/or "Could not reserve enough space for object heap"
# and/or "out of memory", try to set vm.overcommit_memory = 1 temporarily, and/or avoid "-j" build,
# and/or add more memory and then rebuild.
# On mac os, you will probably see this error: "'openssl/ssl.h' file not found". 
# "brew link openssl --force" should be able to solve the issue.
make -j8
 
# Install HAWQ
make install

Init/Start/Stop HAWQ

# Before initializing HAWQ, you need to install HDFS and make sure it works.

source /hawq/install/path/greenplum_path.sh

# Besides you need to set password-less ssh on the systems.
# Exchange SSH keys between the hosts host1, host2, and host3:
hawq ssh-exkeys -h host1 -h host2 -h host3
hawq init cluster # after initialization, HAWQ is started by default

# Now you can stop/restart/start the cluster by using:  
hawq stop/restart/start cluster
 
# HAWQ master and segments are completely decoupled. So you can also init, start or stop the master and segments separately.
# For example, to init: hawq init master, then hawq init segment
# to stop: hawq stop master, then hawq stop segment
# to start: hawq start master, then hawq start segment
 

Connect and Run basic queries

psql -d postgres
create table t ( i int );
insert into t values(1);
insert into t select generate_series(1,10000);
select count(*) from t;

Query external hadoop data

You will need to use PXF to query external hadoop/hive/hbase data. Refer to PXF Build & Install document.

Test HAWQ

# Unit test. To do unit test, go to the src/backend and run unittest.
cd $CODE_BASE/src/backend
make unittest-check

# Code coverage
cd $CODE_BASE
./configure --enable-coverage --enable-debug (for debug build), or ./configure --enable-coverage (for opt build)
make -j8
make install
run some test to exercise hawq (i.e., unit test, install check, feature test, etc)
make coverage-show to see summary code coverage information in console, and detailed code coverage information in CodeCoverageReport (html format)
make coverage-show filter="./src/backend/executor/nodeAgg.c -d ./src/backend/commands" to see code coverage for specific files or directories
make coverage-reset to clear code coverage statistics
 
# Installcheck-good test. After installing HAWQ, please ensure HDFS work before initializing HAWQ. 
source /install/dir/greenplum_path.sh
hawq init cluster
make installcheck-good

# Feature test
cd $CODE_BASE
make feature-test
cd src/test/feature
./feature-test to run all feature test, or ./feature-test --gtest_filter=TestCommonLib.TestSqlUtil to run test suite TestCommonLib.TestSqlUtil

Running catalog tidycat perl modules

The JSON Perl Module is required to run the set of Perl scripts (src/include/catalog).  The versioned JSON formatted catalog files are stored in tools/bin/gppylib/data/<version>.json.  In order to install the JSON module, the developer will need to make the module available from CPAN.  The following was validated on a Macbook Pro OS X 10.11.6 using the information from the Perl on Mac OSX section (http://www.cpan.org/modules/INSTALL.html).  Below you will see the session which performs the following steps:

  1. Validate JSON module is not in the environment.  Receive appropriate error message.
  2. Run cpan install JSON command to install the JSON Perl module.  In the example below, the module is installed locally (local::lib) and not in the system's Perl installation.
  3. Execute the environment variable updates added to the .bashrc file by the installation process.
  4. Validate the tidycat.pl command can now be run without receiving error.

Note:

  • JSON Module version 2.27 and the latest 2.90 have been used to validate they generate the proper catalog JSON formatted file.
  • The scripts are essentially validating the evaluation of *require JSON* passes otherwise the error message is displayed:
