[GitHub] [accumulo] DomGarguilo opened a new issue #2404: Revise what happens when a mismatch in tablet metadata is discovered

[GitBox <gi...@apache.org>]

DomGarguilo opened a new issue #2404:
URL: https://github.com/apache/accumulo/issues/2404


   As a follow on to #2320, it was suggested that the action taken when a mismatch in tablet metadata is discovered, be revised. Currently, an error is just logged. I wanted to create a ticket to discuss possibilities of what to do in this situation. Below is from the original discussion.
   
   Probably do not want to throw an exception here as it will not lead to anything useful since this is being called by a timer thread.  For now logging the error seems good.  
   
   Would probably be good to look into opening up a follow on issue about taking automated action when this is detected (something more than logging an error). Not sure what automated action would be best to take, but could imagine many possible actions (could make the tablet non-functional, report something on the monitor, etc).
   
   ```suggestion
