Subject [jira] [Commented] (HADOOP-11685) StorageException complaining " no lease ID" during HBase distributed log splitting
Date Tue, 27 Oct 2015 23:54:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14977409#comment-14977409
] 

Chris Nauroth commented on HADOOP-11685:
----------------------------------------

[~onpduo], thanks for digging into that more and explaining the full flow.  I agree that the
lease-holding operations will not trigger similar failures.  This is almost ready to commit,
pending another revision to address what I pointed out in the prior comment.  Thanks!

> This is similar to HADOOP-11523, but in a different place. During HBase distributed log
splitting, multiple threads will access the same folder called "recovered.edits". However,
lots of places in our WASB code did not acquire lease and simply passed null to Azure storage,
which caused this issue.
