    • Release Note:
      Add a feature for replica pinning so that when a replica is pinned in a datanode, it will not be moved by Balancer/Mover. The replica pinning feature can be enabled/disabled by "dfs.datanode.block-pinning.enabled", where the default is false.

      Description

      Currently, run Balancer will destroying Regionserver's data locality.
      If getBlocks could exclude blocks belongs to files which have specific path prefix, like "/hbase", then we can run Balancer without destroying Regionserver's data locality.
