Subject [jira] [Commented] (HDFS-7052) Archival Storage: Add Mover into hdfs script
Date Tue, 16 Sep 2014 17:13:33 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135749#comment-14135749
] 

Jing Zhao commented on HDFS-7052:
---------------------------------

bq. Does mover really need its own _OPTS?

Yes, the Mover scans the whole namespace or specific files/directories to detect block replicas
that need migration, and thus may require much more memory than balancer.

Thanks Nicholas and Allen for the review. I will commit it later today if no more comments.
