This page describes how to build Impala from source and how to configure and run Impala in a single node development environment. 

Prerequisites and Requirements

Hardware Requirements

  • CPU must support at least SSSE3
  • Minimum memory: 16GB
  • Hard disk space: 120GB (for the test data)

Supported Operating Systems

Linux

  • Ubuntu 14.04, 16.04, 18.04
  • CentOS 7
  • See bootstrap_development.sh for other supported versions (this wiki page may be stale).

Building Impala (for developing Impala)

  1. git clone https://gitbox.apache.org/repos/asf/impala.git ~/Impala
  2. cd ~/Impala
  3. export IMPALA_HOME=`pwd`
  4. $IMPALA_HOME/bin/bootstrap_development.sh

Building Impala without Test Data (for testing Impala)

  1. git clone https://gitbox.apache.org/repos/asf/impala.git ~/Impala
  2. cd ~/Impala
  3. export IMPALA_HOME=`pwd`
  4. $IMPALA_HOME/bin/bootstrap_system.sh
  5. source $IMPALA_HOME/bin/impala-config.sh
  6. $IMPALA_HOME/buildall.sh -noclean -notests
  7. $IMPALA_HOME/bin/create-test-configuration.sh -create_metastore -create_sentry_policy_db -create_ranger_policy_db
  8. $IMPALA_HOME/testdata/bin/run-all.sh
  9. $IMPALA_HOME/bin/start-impala-cluster.py

Installing and Configuring Impala (Obsolete)

  1. Install prerequisites

    Use https://github.com/apache/impala/blob/master/bin/bootstrap_development.sh to setup your machine. See that script for list of supported versions.
    By default, bootstrap_development.sh clones Impala in $HOME/Impala. To build Impala in a different directory, set IMPALA_HOME when running bootstrap_development.sh. For example IMPALA_HOME=`pwd` ./bootstrap_development.sh

    If you are running on a platform that is not supported by the above script, you will have to install prerequisites and set up your machine manually. Impala Build Prerequisites has some information that can guide you.

  2. Clone the Impala git repo and change to the new Impala directory.

    git clone https://gitbox.apache.org/repos/asf/impala.git Impala
cd Impala

  3. Set the following environment variables in your `.bashrc` or elsewhere:

    export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export IMPALA_HOME=<path to Impala>
export BOOST_LIBRARYDIR=/usr/lib/x86_64-linux-gnu
export LC_ALL="en_US.UTF-8"

  4. Build Impala.

    # Build Impala and prepare the local mini-cluster (the first time only)
${IMPALA_HOME}/buildall.sh -noclean -skiptests -format

    You may hit an error here in bootstrap_toolchain.py if you are building Impala on an operating system for which prebuilt toolchain binaries are not available. In that case you will need to build native-toolchain from scratch then retry this step.

    Want faster builds?

    Doing a full build of Impala can take quite a while! While you wait, check out Tips for Faster Impala Builds.

  5. Start supporting services.

    # This script starts or restarts the local services required for the test cluster
# including HDFS, HBase, Hive and ZooKeeper. If you hit a problem with this script,
# check the log files in ${IMPALA_HOME}/cluster_logs/ for clues.
${IMPALA_HOME}/buildall.sh -noclean -notests -start_minicluster

  6. Start the Impala cluster.

    source ${IMPALA_HOME}/bin/impala-config.sh # You must source this in your shell before most of the below commands will work.

# The following command will start an Impala cluster with 3 Impala demons, one 
# Statestore and one Catalog demon.
${IMPALA_HOME}/bin/start-impala-cluster.py

  7. Check that everything works correctly.

    source ${IMPALA_HOME}/bin/impala-config.sh # If you didn't already source impala-config.sh in this shell

  9. Recompile and restart the Impala cluster for your changes to take effect. See Tips for Faster Impala Builds for tips on how to do incremental builds.

    # Rebuild both backend and frontend
${IMPALA_HOME}/buildall.sh -skiptests -noclean

source ${IMPALA_HOME}/bin/impala-config.sh # If you didn't already source impala-config.sh in this shell
 # Optional: Rebuild the impala binary only
make -j$IMPALA_BUILD_THREADS impalad
# Optional: Build the Java-side frontend only
make -j$IMPALA_BUILD_THREADS fe
# Restart the Impala cluster
