> I digging into the issue,I found the code snippet in ViewFileSystem.java as
> follows:
> {noformat}
> @Override
> public FileStatus getFileStatus(Path f) throws IOException {
> checkPathIsSlash(f);
> return new FileStatus(0, true, 0, 0, creationTime, creationTime,
> PERMISSION_555, ugi.getUserName(), ugi.getGroupNames()[0],
> new Path(theInternalDir.fullPath).makeQualified(
> myUri, ROOT_PATH));
> }
> {noformat}
> If the node in cluster haven't creat user like
> tangjijun,ugi.getGroupNames()[0] will throw
> ArrayIndexOutOfBoundsException.Because no user mean no group.
> I create user tangjijun on that node. Then the job was executed normally.
> I think this code should check ugi.getGroupNames() is empty.When it is empty
> ,then print some log. Not to throw exception.
