Subject [jira] [Commented] (HADOOP-12885) An operation of atomic fold rename crashed in Wasb FileSystem
Date Fri, 04 Mar 2016 18:57:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15180372#comment-15180372
] 

Chris Nauroth commented on HADOOP-12885:
----------------------------------------

[~liushaohui], interesting...  I think you're right that this one is different.  I have not
seen cases of duplicates showing up in the rename pending list like you showed in the description.
 Cc [~gouravk], [~madhuch-ms], [~onpduo], [~dchickabasapa] to check if any of them have seen
something like this.
