Latest commit e9ab53b May 2, 2016 @timarmstrong timarmstrong Add ninja support for faster incremental builds
Ninja resolves dependencies much faster, so if only a couple of files
are changed "ninja -j ${IMPALA_BUILD_THREADS} impalad" returns within a
second or two, while make can take tens of seconds to resolve all the
dependencies.

This requires ninja to be installed. It is widely available, e.g. in the
ninja-build package on Ubuntu.

Ninja can be enabled by passing "-ninja" to buildall.sh or
make_impala.sh. The same targets should work as with make.

The default Ninja status output is fairly terse. It can be customised
with an environment variable. E.g. I have

export NINJA_STATUS="[%u to run/%r running/%f finished] "

Also fixes a bug in make_impala.sh where invalid arguments were ignored.

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase and Amazon S3.
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate CPU-efficient code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including the Apache Parquet (incubating) project.
  • Apache-licensed, 100% open source.
