Colin Patrick McCabe commented on HDFS-5574:
--------------------------------------------
bq. I set DFSConfigKeys.DFS_CLIENT_USE_LEGACY_BLOCKREADER to true, so
getBlockReader can get RemoteBlockReader rather than RemoteBlockReader2.
oh, sorry, I was confusing this with {{DFS_CLIENT_USE_LEGACY_BLOCKREADERLOCAL}}.
+1.
> Remove buffer copy in BlockReader.skip
