> In HDFS-10943 [~yzhangal] reported that edit log can not be rolled due to 
> unexpected edit logs lingering in the buffer.
> Unable to root cause the bug, I propose that we dump the remaining edit logs 
> in the buffer into namenode log, before crashing namenode. Use this new 
> capability to find the ops that sneaks into the buffer unexpectedly, and 
> hopefully catch the bug.
> This effort is orthogonal, but related to HDFS-11292, which adds additional 
> informational logs to help debug this issue.
