---------------------------------
Assignee: Todd Lipcon
> HA: Error (failed to close file) when uploading large file + kill active NN +
> manual failover
> ---------------------------------------------------------------------------------------------
>
> Key: HDFS-3031
> URL: https://issues.apache.org/jira/browse/HDFS-3031
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha
> Affects Versions: 0.24.0
> Reporter: Stephen Chu
> Assignee: Todd Lipcon
> Attachments: styx01_killNNfailover, styx01_uploadLargeFile
>
>
> I executed section 3.4 of Todd's HA test plan.
> https://issues.apache.org/jira/browse/HDFS-1623
> 1. A large file upload is started.
> 2. While the file is being uploaded, the administrator kills the first NN and
> performs a failover.
> 3. After the file finishes being uploaded, it is verified for correct length
> and contents.
> For the test, I have a vm_template styx01:/home/schu/centos64-2-5.5.qcow2.
> styx01 hosted the active NN and styx02 hosted the standby NN.
> In the log files I attached, you can see that on styx01 I began file upload.
> hadoop fs -put centos64-2.5.5.qcow2
> After waiting several seconds, I kill -9'd the active NN on styx01 and
> manually failed over to the NN on styx02. I ran into exception below. (rest
> of the stacktrace in the attached file styx01_uploadLargeFile)
> 12/02/29 14:12:52 WARN retry.RetryInvocationHandler: A failover has occurred
