Ted Yu commented on HBASE-19841:
--------------------------------
Thanks for the reminder about other tests.
For patch v2, the Configuration instance used by the WAL and the instance used
by testing util have different views of config entries.
This inconsistency may lead to issue down the road.
When I ran TestDefaultMemStore with patch v2 against hadoop3:
{code}
[ERROR]
testShouldFlushMeta(org.apache.hadoop.hbase.regionserver.TestDefaultMemStore)
Time elapsed: 1.184 s <<< ERROR!

{code}
With patch v0, TestDefaultMemStore and TestCompactingMemStore pass against
hadoop3.

> This was due to hbase-server/src/test/resources/hbase-site.xml not being

> of hflush and hsync. Without this config entry,
> StreamLacksCapabilityException is thrown.
