> When a coprocessor throws a runtime exception (e.g. NPE), the regionserver handles this
according to {{hbase.coprocessor.abortonerror}}.
> If the coprocessor was loaded on a specific table, the output in the logs give no indication
as to which table the coprocessor was removed from (or which version, or jarfile is the culprit).
This causes longer debugging and recovery times.
