THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
This page is out of date, but retained in case people want to try setting up Impala from scratch without the automated Chef script.
These instructions are installing the preqrequisite packages and configuration for Impala. Currently we have guides for building on Ubuntu 14.04 and CentOs 6.5.
### Java
Download the Oracle Java 7 JDK.
On Ubuntu 14.04 this can be done with the following commands:
sudo add-apt-repository ppa:webupd8team/java -y
sudo apt-get update -y
# Will have to agree to License
sudo apt-get install oracle-jdk7-installer -y
On CentOs 6.5, [this page has a good guide.](https://www.digitalocean.com/community/tutorials/how-to-install-java-on-centos-and-fedora)

### Required packages
On Ubuntu 14.04
sudo apt-get install git build-essential cmake bison flex pkg-config libsasl2-dev autoconf automake libtool maven subversion doxygen libbz2-dev zlib1g-dev python-pip python-setuptools python-dev libssl-dev libboost-all-dev postgresql liblzo2-dev lzop -y
sudo pip install allpairs pytest pytest-xdist paramiko texttable prettytable sqlparse psutil==0.7.1 pywebhdfs gitpython jenkinsapi boto3
On CentOs 6.5
sudo yum groupinstall "Development Tools"
sudo yum -y install git ant libevent-devel automake libtool flex bison gcc-c++ openssl-devel make cmake doxygen.x86_64 glib-devel python-devel bzip2-devel svn libevent-devel krb5-workstation openldap-devel db4-devel python-setuptools python-pip cyrus-sasl* postgresql postgresql-server ant-nodeps lzo-devel lzop
sudo pip-python install allpairs pytest pytest-xdist paramiko texttable prettytable sqlparse psutil==0.7.1 pywebhdfs gitpython jenkinsapi boto3

##### Configuring Boost
Newer versions of boost need to be configured to work with Impala. Impala relies on certain boost libraries ending with a "-mt" extension. You need to add symlinks to boost_filesystem, boost_regex, and boost_system.
On Ubuntu 14.04
cd /usr/lib/x86_64-linux-gnu
sudo ln -s libboost_filesystem.so libboost_filesystem-mt.so
sudo ln -s libboost_filesystem.a libboost_filesystem-mt.a
sudo ln -s libboost_system.so libboost_system-mt.so
sudo ln -s libboost_system.a libboost_system-mt.a
sudo ln -s libboost_regex.so libboost_regex-mt.so
sudo ln -s libboost_regex.a libboost_regex-mt.a
On CentOS 6.5
cd /usr/local/lib
sudo ln -s libboost_filesystem.so libboost_filesystem-mt.so
sudo ln -s libboost_filesystem.a libboost_filesystem-mt.a
sudo ln -s libboost_system.so libboost_system-mt.so
sudo ln -s libboost_system.a libboost_system-mt.a
sudo ln -s libboost_regex.so libboost_regex-mt.so
sudo ln -s libboost_regex.a libboost_regex-mt.a
##### Configuring Postgresql
If you are installing Impala on a fresh machine, you'll need to initialize postgres. On CentOs 6.5 this can be done by running
sudo service postgresql initdb
You need to make a configurations change to allow Hbase and the Hive metastore to functions correctly. Edit the following file as root.
On Ubuntu 14.04
/etc/postgresql/*/main/pg_hba.conf
On CentOs 6.5
/var/lib/pgsql/data/pg_hba.conf
In the following lines at the end of the file, change `peer` or `ident` to `trust`.
# Database administrative login by UNIX sockets
local all all ident
# TYPE DATABASE USER CIDR-ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all ident
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
To make Postgres aware of these changes, either restart the service or run: pg_ctl reload
##### Creating the Hive metastore user
sudo -u postgres psql postgres
Then, at the `postgres` command prompt:
CREATE ROLE hiveuser LOGIN PASSWORD 'password';
ALTER ROLE hiveuser WITH CREATEDB;

### Maven 3
wget http://www.interior-dsgn.com/apache/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.tar.gz
tar xvf apache-maven-3.0.5-bin.tar.gz && sudo mv apache-maven-3.0.5 /usr/local
---
### Environment variables
Put these in your `.bashrc` or elsewhere:
On Ubuntu 14.04
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export IMPALA_HOME=<path to Impala>
export BOOST_LIBRARYDIR=/usr/lib/x86_64-linux-gnu
export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
export LC_ALL="en_US.UTF-8"
export M2_HOME=/usr/local/apache-maven-3.0.5
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
On CentOs 6.5
export BOOST_ROOT=/usr/local

### Add a path for HDFS domain sockets
sudo mkdir /var/lib/hadoop-hdfs/
sudo chown <user> /var/lib/hadoop-hdfs/
----
### Start local ssh server
sudo service ssh start
----
### Enable password-less SSH for HBase
ssh-keygen -t dsa
# Do not type in any passkey. Just press enter.
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
---
### Setup NTP for Kudu
On CentOS 7
yum install ntp
systemctl start ntpd
