Subject [jira] [Updated] (HBASE-13128) Make HBCK's lock file retry creation and deletion
Date Thu, 05 Mar 2015 18:48:38 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13128?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Victoria updated HBASE-13128:
-----------------------------
    Attachment: hbck_files_fix-v4.patch

Fixed the tab character style error. Regarding the long line - its long because parameter
name is long - I think splitting the statement to multi-line will make it less straightforward.
I can assign variable to the value of the parameter and then use it - let me know if this
is really needed.

> 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.
