Andrew Purtell commented on HBASE-12870:
----------------------------------------
Cam we also include the region information for "Timed out waiting for lock for
row". Been dealing with them for the last couple of days. We can find the info
with a stack dump but would be better if the WARN level log line alerting us to
the condition also carries that information.
> "Major compaction triggered" and "Skipping major compaction" messages lack
> the region information

> It should log the store/region information instead. Unfortunately, this
> information seems to be unavailable at this point, so more context needs to
> be supplied while calling {{RatioBasedCompactionPolicy.isMajorCompaction()}}.
