> --------------------------------------------------------------------

> Key: HDFS-8541
> URL: https://issues.apache.org/jira/browse/HDFS-8541
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer & mover
> Reporter: Tsz Wo Nicholas Sze
> Assignee: surendra singh lilhore
> Priority: Minor
>
> HDFS-8143 changed Mover to exit after some retry when failed to move blocks.
> Two additional suggestions:
> # Mover retry counter should be incremented only if all moves fail. If there
> are some successful moves, the counter should be reset.
> # Mover should exit with NO_MOVE_PROGRESS instead of IO_EXCEPTION in case of
> failure.
