> dead lock occurs when rolleditlog rpc call happen and editPendingQ is full
> --------------------------------------------------------------------------
>
> Key: HDFS-13051
> URL: https://issues.apache.org/jira/browse/HDFS-13051
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.7.5
> Reporter: zhangwei
> Assignee: Daryn Sharp
> Priority: Major
> Labels: AsyncEditlog, deadlock
> Attachments: HDFS-13112.patch, deadlock.patch
>
>
> when doing rolleditlog it acquires fs write lock，then acquire FSEditLogAsync
> lock object，and write 3 EDIT(the second one override logEdit method and
> return true)
> in extremely case，when FSEditLogAsync's logSync is very
> slow，editPendingQ(default size 4096)is full，it case IPC thread can not offer
> edit object into editPendingQ when doing rolleditlog，it block on editPendingQ
> .put method，however it does't release FSEditLogAsync object lock, and
> edit.logEdit method in FSEditLogAsync.run thread can never acquire
> FSEditLogAsync object lock, it case dead lock
> stack trace like below
