> {{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}}.
