Re: RE: Making Mumak work with capacity scheduler

Yes Devaraj,
>From the logs, looks it failed to create /jobtracker/jobsInfo



code snippet:

if (!fs.exists(path)) {
        if (!fs.mkdirs(path, new FsPermission(JOB_STATUS_STORE_DIR_PERMISSION))) {
          throw new IOException(
              "CompletedJobStatusStore mkdirs failed to create "
                  + path.toString());
        }

@ Arun, Can you check, you have correct permission as Devaraj said?
