----------------------------------------------------------------
This may be naive, because I don't have a deep understanding of the minicluster
in particular, but regionservers running under separate user accounts is unlike
the typical deployment, right? in which all regionservers are likely to be
running under the same service account, probably named "hbase".

> HBASE-7636 makes some TestDistributedLogSplitting pass consistently by
> disabling hdfs short circuit reads.
> HBASE-8349 makes datanode node death recovery pass consistently by disabling
> hdfs short circuit reads.
> This will likely require configuration modifications to fix and may have
> different fixes for hadoop1, hadoop2 (HDFS-2246), and hadoop3 (HDFS-347)...
