> Fully qualified intermediate done directory will break per-user dir creation

> Key: MAPREDUCE-6044
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6044
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver
> Affects Versions: 3.0.0, 2.6.0
> Environment: Windows
> Reporter: Zhijie Shen
> Assignee: Zhijie Shen
> Attachments: MAPREDUCE-6044.1.patch
>
>
> After MAPREDUCE-6032, the string of the intermediate done dir will be a fully
> qualified path.
> The following code in JobHistoryUtils tries to concat this path and user name
> to create a per-user dir path, using File.separator as the seperator (on
> Windows, it is "\").
> {code}
> public static String getHistoryIntermediateDoneDirForUser(Configuration
> conf) throws IOException {
> return getConfiguredHistoryIntermediateDoneDirPrefix(conf) +
> File.separator
> + UserGroupInformation.getCurrentUser().getShortUserName();
> }
> {code}
> Therefore, an intermediate done dir for user will become
> "hdfs://localhost:9201/mapred/history/done_intermediate\user". With the
> scheme available in the path, Path class will not replace "\" with "/", and
> finally FS cannot handle this path correctly: it will take
> "done_intermediateuser" as a single directory name.
