How to build Impala

First make sure you have all the prerequisites for Impala installed and ready.

Building Impala

Building Impala for the first time

The first time only, do:

./buildall.sh -skiptests -build_shared_libs -format

The -format parameter tells Impala to create the Hive metastore and format the HDFS namenode, as well as produce the configuration for the rest of the cluster.

Building Impala subsequently

After this, you can use

./buildall.sh -skiptests -build_shared_libs
