Jingcheng Du commented on HBASE-13021:
--------------------------------------

In the HDFS-6133, it is guaranteed by setting the dfs.datanode.block-pinning.enabled as true and adding favored nodes.
HFiles currently have the favored nodes, does it mean "Pin regions blocks to avoid HDFS balancing" could be implemented by only setting the dfs.datanode.block-pinning.enabled as true?

> Now that HDFS-6133 is into HDFS, we might want to implement its features to pin regions blocks to avoid them to be re-located.
