Zhan Zhang commented on HBASE-14795:
------------------------------------

[~jmhsieh] Thanks for bring this up. I am working on HBASE-14849, and also doing some cleanup
work, which will also fix following warnings.
warning: there were 3 feature warning(s); re-run with -feature for details

Regarding below warning, it is a legacy one and HBASE-14159 has already open for it.
warning: Class org.apache.hadoop.mapred.MiniMRCluster not found - continuing with a stub.

for a more custom scan implementation that will make the following use case more effective.

> In the case you have multiple scan ranges on a single table with in a single query. 
TableInputFormat will scan the the outer range of the scan start and end range where this
implementation can be more pointed.
