> ------------------------------------------------
>
> Key: HADOOP-118
> URL: http://issues.apache.org/jira/browse/HADOOP-118
> Project: Hadoop
> Type: Bug
> Components: dfs
> Versions: 0.1.0
> Environment: 195 node cluster running redhat linux (2.6 kernel)
> Reporter: Owen O'Malley
> Assignee: Owen O'Malley
> Priority: Critical
> Fix For: 0.2
> Attachments: release-create-locks.patch
>
> In some failure modes, the pending creates list is not cleaned up and
> prevents that file from ever being created.
> When I try to create the file after the first job was killed (hours
> previously), I get:
> 060404 084619 Cannot start file because pendingCreates is non-null.
