...
- You want to build Impala purely from source without relying on prebuilt binaries.
- You are trying to build Impala on a platform for which prebuilt binaries are not available.
You want to add or modify a dependency in native-toolchain. E.g. build Impala with a newer version of LLVM, or with different configuration options.
A number of prerequisites are required to build the full toolchain.

cd ${IMPALA_HOME}

# Optional: ${IMPALA_HOME}/toolchain is the default value for IMPALA_TOOLCHAIN. You may want to add this to your .bashrc file.
export IMPALA_TOOLCHAIN=${IMPALA_HOME}/toolchain
# Build Impala - this will pick up the new toolchain.
