Subject [jira] [Commented] (HBASE-5136) Redundant MonitoredTask instances in case of distributed log splitting retry
Date Fri, 13 Jan 2012 17:44:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13185693#comment-13185693

Zhihong Yu commented on HBASE-5136:

This is similar to Prakash's suggestion.
In some situation, several (aborted) tasks for the same server would be shown on master UI
at the same time since it takes 1 minute to clean up task display.

> In case of log splitting retry, the following code would be executed multiple times:
> {code}
>   public long splitLogDistributed(final List<Path> logDirs) throws IOException
>     MonitoredTask status = TaskMonitor.get().createStatus(
>           "Doing distributed log split in " + logDirs);
> {code}
> leading to multiple MonitoredTask instances.
> User may get confused by multiple distributed log splitting entries for the same region
