> of HBASE-15120 against branch-1.1, we could see below failure:
> {noformat}
> testIncrementWithReturnResultsSetToFalse(org.apache.hadoop.hbase.regionserver.wal.TestDurability)
> Time elapsed: 0.111 sec <<< FAILURE!
> java.lang.AssertionError: expected null, but
> was:<keyvalues={row1/family:col1/1452864457248/Put/vlen=8/seqid=4}>
> at org.junit.Assert.fail(Assert.java:88)
> at org.junit.Assert.failNotNull(Assert.java:755)

> at
> org.apache.hadoop.hbase.regionserver.wal.TestDurability.testIncrementWithReturnResultsSetToFalse(TestDurability.java:215)
> {noformat}
> Checking the history, this should be a regression caused by HBASE-15031, and
> confirmed the UT could pass before commit c5cfea4e37a.
> Reason of the failure is HBASE-15031 introduced the
> {{hbase.increment.fast.but.narrow.consistency}} flag which is *false* by
> default, but forget to set it in
> TestDurablity#testIncrementWithReturnResultsSetToFalse
