Beata Sudi updated HBASE-23670:
-------------------------------
Description:
testShutDownFixupWhenDaughterHasSplit is flaky.
I had a look at it, it fails because the compaction isn't ready when the
assertion is called. The function HRegion.compact() has a comment that it can
block for a long time, do not use it for a time-sensitive thread.
edit: also found a weird debug message, it can also be a problem:
~compactions.SortedCompactionPolicy(231): Not compacting files because we only
have 0 files ready for compaction. Need 3 to initiate.~

I had a look at it, it fails because the compaction isn't ready when the
assertion is called. The function HRegion.compact() has a comment that it can
block for a long time, do not use it for a time-sensitive thread. I think there
should be a bit more waiting before the assertion is called (and probably the
for loop with Thread.wait() could be improved as well)
