Evans Ye commented on BIGTOP-1752:
----------------------------------

Hey [~Jonathan Kelly], sorry for the late review.
I've tried the patch but it can not be directly applied, so please rebase.
I did some tweak at my local to test the feature and I got consistent result like you reported in the description by leveraging zinc to build. 
Just one more thing: since the feature requires a manual step to start the daemon, please add words in our readme so that people may know how to use. Thanks!

> The Zinc Nailgun server can be used to speed up compilation of Scala projects (like Spark) considerably.  For example, building Spark without Zinc running takes about 26 mins in my experience, but with Zinc running it takes only about 14 mins.
> This patch causes Zinc to be installed in /usr/local/zinc by the bigtop_toolchain, though it must still be started by whatever process (e.g., Jenkins) executes the build by running "/usr/local/zinc/bin/zinc -start" before kicking off the build.
> See https://github.com/typesafehub/zinc and http://spark.apache.org/docs/latest/building-spark.html#speeding-up-compilation-with-zinc for more information about Zinc and using it with a Spark build.
