> {{FsShell}}'s top level exception handler catches and displays exceptions.  Unfortunately
it displays only the first line of an exception, which means an unexpected {{RuntimeExceptions}}
like {{NullPointerException}} only display "{{cmd: NullPointerException}}".  This user has
no context to understand and/or accurately report the issue.
> Found due to bugs such as {{HADOOP-7327}}.
