Kihwal Lee commented on HDFS-2828:
----------------------------------
I recently heard of a related case. According to Rohini who has dealt with this
problem in the past, the delete issued after failed/interrupted create may also
fail due to a short NN outage. In this case, the lease is kept being renewed
and normal retry won't work. It appears the client-side lease handling needs a
bit of improvement.

> Key: HDFS-2828
> URL: https://issues.apache.org/jira/browse/HDFS-2828
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Todd Lipcon
>
> If you run "hadoop fs -put - foo", write a few lines, then ^C it from the
> shell, about half the time you will get a LeaseExpiredException. It seems
> like the shell is first calling {{delete()}} on the file, then calling
> {{close()}} on the stream. The {{close}} call fails since the {{delete}} call
> kills the lease. I saw this on trunk but my guess is that it affects 23 also.
