Subject [jira] [Commented] (HBASE-15291) FileSystem not closed in secure bulkLoad
Date Mon, 11 Jul 2016 18:03:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15371299#comment-15371299

Jerry He commented on HBASE-15291:
----------------------------------

There is a race condition caused by this fix and it is risky.

For example, the same region server hosting two regions: region1 and region2.
Secure bulkload calls into both region1 and region2.  
The calls are from the same UGI so they will share the same fs.  If one region finishes earlier,
it will close the bulk load fs, and the other region will fail.
