   **Is your feature request related to a problem? Please describe.**
   
   The manager constantly scans the metadata table in TabletGroupWatcher code which runs the tablet management iterator to do tserver side filtering.  When a tablet w/ illegal data is encountered by this scan it can cause the following to happen.
   
    * exception is thrown on the tserver side
    * manager reports exception was thrown on tserver X
   
   To find the issue need to look in manager logs and then tserver logs. The tserver logs may or may not contain the metadata row that caused the exception.  Without this row it is much harder to track down the cause of the exception.
   
   **Describe the solution you'd like**
   
   Ideally when this happens a log a message that includes the tablet end row and error would be emitted.  To make tracking the problem down easier, it could be propagated to the manager logs.  At the very least the tserver log message should attempt to include the row.
