Vishal Khandelwal commented on HBASE-20940:
-------------------------------------------
Thanks [~apurtell] for looking into it and running the test. I am not sure why
my previous run did not show "org.apache.hadoop.hbase.regionserver.TestHRegion"
at all :( [^result_HBASE-20940.branch-1.v2.log] .
I have attached the latest patch fixing the TestHRegion#testMerge and following
are the results. Full run also seems fine to me now.

> a split of a region who still has references to its parent. More details
> about scenario can be found here HBASE-20933
> HStore.hasReferences should check from fs.storefile rather than in memory
> objects.
