------------------------------------------------
In JMS's attached output I could see this
{code}
2018-01-13 17:45:52,842 DEBUG [Time-limited
test-inmemoryCompactions-1515883552809] regionserver.CompactionPipeline(206):
Compaction pipeline segment Type=CSLMImmutableSegment, empty=no, cellCount=3,
cellSize=6291588, totalHeapSize=6292080, min timestamp=1515883552790, max
timestamp=1515883552819Num uniques -1; flattened
{code}
In a successful run I get this
{code}
Compaction pipeline segment Type=CSLMImmutableSegment, empty=no, cellCount=2,
cellSize=4194392, totalHeapSize=4194792, min timestamp=1517265194295, max
timestamp=1517265194298Num uniques -1; flattened
{code}
In a successful run first we get cellCount = 1 and then the next inmemory flush
creates cellCount = 2.
In the case of the failed test run the cellCount = 3.
Also this test requires some clean up. The HTD and region are created for every
test case and in tear down there is no clean up of the region or deletion of
the region. Cleaning up is better.
