[jira] [Commented] (HBASE-8749) Potential race condition between
FSUtils.renameAndSetModifyTime() and HFile/LogCleaner
[ https://issues.apache.org/jira/browse/HBASE-8749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13684762#comment-13684762 ]
Ted Yu commented on HBASE-8749:
-------------------------------
I was thinking of the same solution.
Can you run patch through test suite - Hadoop QA was having trouble with test run.
Thanks, Matteo.

> One scenario that could have led to the above exception was that the LogCleaner thread deleted the log file which had just been moved to .oldlogs dir before the call to fs.setTimes() executed.
> When fs.setTimes() ran, the file was no longer there.
