> '._COPYING_' sufix temp file could prevent from running MapReduce job

> Key: HADOOP-9750
> URL: https://issues.apache.org/jira/browse/HADOOP-9750
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Kousuke Saruta
> Fix For: 3.0.0

> Attachments: HADOOP-9750.patch
>
>
> FsShell copy/put creates staging files with '._COPYING_' suffix.
> When we run MapReduce job during being the temp file, the job could fail
> because the temp file is not invisible from MapReduce job.
> Now, I suggest to rename the temp file with '_' suffix such like
> '_*._COPYING_'.
