Anoop Sam John commented on HBASE-22387:
----------------------------------------
bq.I found anther problem : seems always use the BlockReaderRemote to read the
block in my testing cluster (see blockReaderRemote), actually it's should use
LocalBlockReader because all of the locallity are 1.0. Let me have a check.
Did u config the SCR correctly in RS and DN side? The RS could load the native
hadoop so? Can check in logs.
