Subject [jira] [Commented] (HDFS-9151) Mover should print the exit status/reason on console like balancer tool.
Date Mon, 28 Sep 2015 15:18:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14933430#comment-14933430

Daniel Templeton commented on HDFS-9151:
----------------------------------------

Thanks, [~surendrasingh].  I have a couple of language edits:

bq. Failed to move some blocks after N retry. Exiting...

Since the default is 10 retries, it's probably safe to assume the retry count will be >
1:

"Failed to move some blocks after N retries. Exiting..."

bq. Mover Successful, all blocks satisfying the specified storage policy. Exiting...

Tense and grammar:

"Mover Successful: all blocks satisfy the specified storage policy. Exiting..."
