Subject [jira] Commented: (HADOOP-5672) Use custom MAX_SIZE_TO_MOVE value Balancer
Date Thu, 16 Apr 2009 23:33:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699925#action_12699925
] 

Hairong Kuang commented on HADOOP-5672:
---------------------------------------

1. better set the initial value of maxSizeToMove to be MAX_SIZE_TO_MOVE;
2. since maxSizeToMove is a field of Balancer, there is no need to change any method signature.
3. description of the property dfs.balancer.maxSizeToMove shoud specify that this is the max
number of bytes to move per iteration.
