Sergey Shelukhin updated HIVE-4239:
-----------------------------------
Attachment: HIVE-4239.patch
Made it specific to HS2 and configurable in case bugs are found.
The provided unit test passes; I also tried it with explain queries on HS2 on a
cluster here, submitting from 5-20 threads (same explain), and it appears to
work; I can also see logs showing compile is parallel, and corresponding
increase in throughput
> Remove lock on compilation stage
