Unknown Error

There are several causes for this error. Some common causes are:

• There are user accounts on your cluster that have a user ID less than the value specified for the min.user.id property in the container-executor.cfg file. The default value is 1000 which is appropriate on Ubuntu systems, but may not be valid for your operating system. For information about setting min.user.id in the container-executor.cfg file, see this step.
• This error is often caused by previous errors; look earlier in the log file for possible causes.
