Subject [jira] [Updated] (HBASE-13128) Make HBCK's lock file retry creation and deletion
Date Sat, 28 Feb 2015 03:55:05 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.patch

I have added retries for both creation and deletion of the lock file.
The default number of attempts is set to 5 with the initial sleep time between the attempts
set to 200 msec.

> 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.
