(Updated 2011-09-23 01:39:08) bq. bq. bq. Review request for hbase, Gary Helmling and Mingjie Lai. bq. bq. 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. bq. https://issues.apache.org/jira/browse/HBASE-4014 bq. bq. bq.
