Anoop Sam John commented on HBASE-8009:
---------------------------------------
[~stack] Most of the failed cases I can see a failure with
TestBulkDeleteProtocol#testBulkDeleteColumn(). Here in the test I am deleting
100 rows and asserting that against what the HTable#coprocessorExec() returned
me. This in the failed case coming as 120 instead of 100. In test I have total
5 regions in table with 20 rows each. So one region entry coming as duplicate
in the Map (return value from HTable#coprocessorExec () )!!! Some retry
issue!!!( ? )
I started digging in the coprocessorExec() code more.. Seems there are some
bugs in that area. Let me explore. BTW will it be good that I add some logs in
the test case about the returned Map from coprocessorExec() and give a patch.
Can we commit so that the next failed time we can get more clear picture about
our doubt?
> Fix and reenable the hbase-example unit tests.

> The unit tests pass locally for me repeatedly but fail from time to time up
> on jenkins. HBASE-7994 disabled them. This issue is about spending the time
> to make sure they pass up on jenkins again. They have been disabled because
> unit tests have been failing way more often than they have been passing over
> the last few months and we want to establish passing tests as the precedent
> again. Once that is in place, we can work on bringing back examples.
