-----------------------------------------
Summary: Mover should exit with NO_MOVE_PROGRESS if there is no
move progress
Key: HDFS-8541
URL: https://issues.apache.org/jira/browse/HDFS-8541
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Tsz Wo Nicholas Sze
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.
