> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5264
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 3.0.0, 2.1.0-beta
> Reporter: Rémy SAISSY
> Attachments: MAPREDUCE-5264.20130607.1.patch
>
>
> According to https://issues.apache.org/jira/browse/HADOOP-9438,
> FileSystem#mkdirs and FileContext#mkdir do not throw
> FileAlreadyExistsException if the directory already exist.
> Some places in the mapreduce codebase assumes FileSystem#mkdirs or
> FileContext#mkdir throw FileAlreadyExistsException.
> At least the following files are concerned:
> - YarnChild.java
> - JobHistoryEverntHandler.java
> - HistoryFileManager.java
> It would be good to re-review and patch this if needed.
