Appy updated HBASE-17732: ------------------------- Status: Open (was: Patch Available) > Add CpType template to CoprocessorEnvironment > --------------------------------------------- > > Key: HBASE-17732 > URL: https://issues.apache.org/jira/browse/HBASE-17732 > Project: HBase > Issue Type: Improvement > Reporter: Appy > Assignee: Appy > Attachments: HBASE-17732.master.001.patch, > HBASE-17732.master.002.patch > > > Adding template for coprocessor type to CoprocessorEnvironment will: > - get rid of 'instanceOf' checks we do in various coprocessor hosts > - allow us to load only relevant coprocessors in hosts (right now i think > each host loads all coprocs and it's only during execOperation that it checks > if the coproc is of correct type ie XXCoprocessorHost will load XXObserver, > YYObserver, and all others, and in will check in execOperation if coproc is > of type XXObserver and ignore the rest). > - allow sharing of a bunch functions/classes which are currently 99% > duplicate of each other. For eg. CoprocessorOperations, > CoprocessorOperationWithResult, execOperations(). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
