bq. Summary
bq. -------
bq.
bq. https://issues.apache.org/jira/browse/HBASE-4014 Coprocessors: Flag the
presence of coprocessors in logged exceptions
bq.
bq. The general gist here is to wrap each of
{Master,RegionServer}CoprocessorHost's coprocessor call inside a
bq.
bq. "try { ... } catch (Throwable e) { handleCoprocessorThrowable(e) }"
bq.
bq. block.
bq.
bq. handleCoprocessorThrowable() is responsible for either passing 'e' along
to the client (if 'e' is an IOException) or, otherwise, aborting the service
(Regionserver or Master).
bq.
bq. The abort message contains a list of the loaded coprocessors for crash
analysis.
bq.
bq.
bq. This addresses bug HBASE-4014.
