Alexey Serbin updated KUDU-3780:
--------------------------------
Description:
At the time of writing, the regular build flow assumes building all the
3rd-party components to produce libkudu_client.so bits. For projects like
Impala, libkudu_client.so is the only required artifact, and they need building
it with a custom/specific toolchain, so sharing pre-built 3rd-party bits built
a standard way it's done in Kudu isn't a viable option (i.e. Impala needs
Kudu's 3rd-party components built with Impala-specific toolchain).
To reduce build times for libkudu_client as an artifact needed by Impala, it
makes sense to provide a way building only 3rd-party components needed for
libkudu_client (at least, for DEBUG and RELEASE build configurations). That
might be implemented as a change in build scripts' behavior when a particular
environment variable specified (e.g., {{KUDU_CLIENT_ONLY}}).
