log ?

>                 URL: https://issues.apache.org/jira/browse/HBASE-17817
>             Project: HBase
>          Issue Type: Improvement
>          Components: Coprocessors, regionserver
>    Affects Versions: 1.1.2
>            Reporter: Steen Manniche
>              Labels: logging
>
> When a coprocessor throws a runtime exception (e.g. NPE), the regionserver handles this
according to {{hbase.coprocessor.abortonerror}}.
> 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.
