Sean Busbey commented on HBASE-25449:
-------------------------------------
we definitely still need to document the importance of short circuit reads, but
we should do that in the text of the reference guide and not in the config
files.
> 'dfs.client.read.shortcircuit' should not be set in hbase-default.xml

> I think this parameter is not suitable for in hbase-default.xml, because in

> rely on HDFS configuration, the parameters in hbase service still is
> false.Must be explicitly in hbase-site.xml is set to
