Subject [jira] [Commented] (HBASE-12480) Regions in FAILED_OPEN/FAILED_CLOSE should be processed on master failover
Date Sat, 15 Nov 2014 03:47:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14213334#comment-14213334

Jimmy Xiang commented on HBASE-12480:
-------------------------------------

I see. 

{noformat}
 +                && serverName != null && onlineServers.contains(serverName))
{
{noformat}
No need this change. If serverName is null, onlineServers should not contain it.

bq. isServerOnline(ServerName) will return false when serverName is null (It will be null
in case 2 above)
In master branch, the server should be never null if it is in these states.

{noformat}
+      case FAILED_CLOSE:
+      case FAILED_OPEN:
+        unassign(regionInfo, regionState.getServerName(), null);
...
{noformat}
Should use invokeUnAssign.

do the same
