Zhijie Shen created MAPREDUCE-6044: -------------------------------------- Summary: Fully qualified intermediate done directory will break per-user dir creation on Windows 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
After MAPREDUCE-6032, the string of the intermediate done dir will be a fully qualified path. The following code in JobHistroyUtils 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
