Hi All,
A consistent piece of feedback from Spark developers has been that the
Maven build is very slow. Typesafe provides a tool called Zinc which
improves Scala complication speed substantially with Maven, but is
difficult to install and configure, especially for platforms other
than Mac OS.
I've just merged a patch (authored by Brennon York) that provides an
automatically configured Maven instance with Zinc embedded in Spark.
E.g.:
./build/mvn -Phive -Phive-thriftserver -Pyarn -Phadoop-2.3 package
It is hard to test changes like this across all environments, so
please give this a spin and report any issues on the Spark JIRA. It is
working correctly if you see the following message during compilation:
[INFO] Using zinc server for incremental compilation
Note that developers preferring their own Maven installation are
unaffected by this and can just ignore this new feature.
Cheers,
- Patrick
