How to Build
Setup an environment with the dependencies installed
Install dependencies on MAC (with xcode installed)
brew install protobuf protobuf-c Gsasl openssl boost thrift json-c ccache snappy libyaml libevent python brew tap brona/iproute2mac brew install iproute2mac brew install postgresql brew install cmake sudo pip install pygresql==4.0 (make sure specified version 4.0) sudo pip install unittest2 pycrypto lockfile paramiko psi pyyaml sudo pip install http://sourceforge.net/projects/pychecker/files/pychecker/0.8.19/pychecker-0.8.19.tar.gz/download sudo pip install http://darcs.idyll.org/~t/projects/figleaf-0.6.1.tar.gz brew uninstall postgresql
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
Xcode includes the tools, compiler and SDK for building HAWQ.
Install dependencies on CentOS 7.X

Build dependencies yourself ( tested on Redhat 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.
| Name | Version | Download URL |
|---|---|---|
| | http://sourceforge.net/projects/boost/files/boost/1.56.0/boost_1_56_0.tar.bz2 |
| | http://archive.apache.org/dist/thrift/0.9.1/thrift-0.9.1.tar.gz |
| | https://github.com/google/protobuf/tree/v2.5.0 |
| | http://www.curl.haxx.se/download/curl-7.44.0.tar.gz |
You might need to run "ldconfig -p <LIBRARY_INSTALL_PATH>" after installing them.
For thrift build, you might need "--without-tests" for configure.

You will need to install python packages same as those which are required for Redhat/centos 7.

Build with Prebuilt Docker Image
Probably the simplest way to get started with the build is starting with the community developed docker image with all the project dependencies pre-installed.
To use the docker image follow the steps on: https://hub.docker.com/r/mayjojo/hawq-devel/
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 redhat/centos6.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.h.
" 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.
Your need to verify your HDFS works.
# start HDFS start-dfs.sh # Do some basic tests to make sure HDFS works hadoop fs -lr / hadoop fs -mkdir /test hadoop fs -put ./testfile / hadoop fs -get /testfile .
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) ./configure --prefix=/hawq/install/path --with-python --with-perl # You can also run the command with --help for more configuration. ./configure --help #Note: If ./configure complains that libyarn is missing, it is provided under ./depends/libyarn. # Please follow the above steps to install libyarn. You may need to run "ldconfig -p <PATH>" after libyarn is installed. # 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 error like # "Error occurred during initialization of VM" "Could not reserve enough space for object heap"; # 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 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;
Test HAWQ
# Unit test. To do unit test, go to the src/backend and run unittest. cd $CODE_BASE/src/backend make unittest-check # 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
