Steen Manniche commented on HBASE-17817:
----------------------------------------
Thank you for the elaborate comments. As per your suggestion on hbase-user, I
created a review-board issue and continued the development of the patch there.
With regards to the {{isAssignableFrom}} comment: you are absolutely right, and
I will make that part of the patch.
> Make Regionservers log which tables it removed coprocessors from when aborting
> ------------------------------------------------------------------------------

> Key: HBASE-17817
> 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
> Attachments: HBASE-17817.master.001.patch,

>
> 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.
