Michael Brown updated IMPALA-7241:
----------------------------------
Description:
During a stress test with 8 nodes running an insecure debug build based off
master, an impalad hit a DCHECK. The concurrency level at the time was between
150-180 queries.
The DCHECK was {{progress-updater.cc:43] Check failed: delta >= 0 (-3 vs. 0)}}.
The stack was:
