Subject [jira] [Commented] (HBASE-13128) Make HBCK's lock file retry creation and deletion
Date Fri, 27 Feb 2015 23:06:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14340988#comment-14340988

Elliott Clark commented on HBASE-13128:
---------------------------------------

This is all about removing the file. The call to HDFS can fail and throw an error. That will
leave the lock file since there's no retires.

> When hbck runs it creates a lock file to ensure that no two hbck instances are running.
We've been seeing creating and removing that file fail sometimes.
> This improvement should make the creation, closing of the file, and the deletion retry
multiple times. This should allow our alerting which uses this command to be more reliable
and have fewer false positives.
