Chris Nauroth updated MAPREDUCE-6044:
-------------------------------------
Description:
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.
