Thank you for the direction.

Subject: Re: Increase Timeout or optimize Spark UT?

It seems like it's time to look into how to cut down some of the test runtimes. Test runtimes
will slowly go up given the way development happens. 3 hr is already a very long time for
tests to run.

Hi, All.

Recently, Apache Spark master branch test (SBT with hadoop-2.7 / 2.6) has been hitting the
build timeout.

Please see the build time trend.

All recent 22 builds fail due to timeout directly/indirectly. The last success (SBT with Hadoop-2.7)
is 15th August.

We may do the followings.

  1.  Increase Build Timeout (3 hr 30 min)
  2.  Optimize UTs (Scala/Java/Python/UT)

But, Option 1 will be the immediate solution for now . Could you update the Jenkins setup?
