Hi! Some ideas to mitigate the queue issues:
1. Disable the alternate JDK/Hadoop tests for the precommit PR (any problems would still be discovered later in the nightlies) 2. Stagger the nightly tests: Run 2.5 and 2.6 on odd days, and branch-2 , branch-3 and master on even days The first one is quite simple to do, the second one would be a little more involved. WDYT ?
