Subject [jira] [Commented] (HBASE-5677) The master never does balance because duplicate openhandled the one region
Date Mon, 09 Apr 2012 13:53:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13249821#comment-13249821
] 

Zhihong Yu commented on HBASE-5677:
-----------------------------------

There is this method in HMasterInterface:
{code}
  /** @return true if master is available */
  public boolean isMasterRunning();
{code}
If we introduce isMasterAvailable(), that would create confusion, right ?

> If region be assigned When the master is doing initialization(before do processFailover),the
region will be duplicate openhandled.
> because the unassigned node in zookeeper will be handled again in AssignmentManager#processFailover()
> it cause the region in RIT,thus the master never does balance.
