dhruba borthakur updated HADOOP-1583:
-------------------------------------
Component/s: dfs
> AlreadyBeingCreatedException because pendingCreates is non-null
> ---------------------------------------------------------------
>
> Key: HADOOP-1583
> URL: https://issues.apache.org/jira/browse/HADOOP-1583
> Project: Hadoop
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.9.2
> Reporter: Konstantin Shvachko
> Priority: Blocker
> Fix For: 0.14.0
>
>
> When a client lease expires the lease monitor removes it from the list of
> leases, but
> does not release pendingCreates files. When the name-node sees a file in
> pendingCreates
> which does not have a lease for the original client it throws
> AlreadyBeingCreatedException.
> This was reported in several issues like HADOOP-1411, but has never been
> resolved.
> I see two approaches:
> # clean pendingCreates when leases expire, or
> # reuse entries in pending creates for which there are no lease.
> The first is preferable imo since it cleans memory at the right time.
