Description

When there is an error in shared edits dir then current policy requires the active name node to abort and shutdown.
Currently there is no way to shut down the name node and hence this does not happen even after all journals have been aborted on error. In fact the name node stays Active and also is not in safe mode. Ideally it should shut down, or at least go into safe mode or standby mode.
