Suresh Srinivas commented on HDFS-4148:
---------------------------------------
bq. I actually prefer the name getMutableX variant. I think long method names
should not be used as substitute for javadoc which describes functionality. My
preference is to either stick to getXYZMutable or getMutableXYZ.
Also getXYZNotRO or getXYZNonRO is also okay.
