Subject [jira] [Commented] (HBASE-11733) Avoid copy-paste in Master/Region CoprocessorHost
Date Fri, 15 Aug 2014 18:03:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098845#comment-14098845
] 

Lars Hofhansl commented on HBASE-11733:
---------------------------------------

bq. execOperation(coprocessors.isEmpty() ? null : new CoprocessorOperation()

+1 on that. Normally this would not even be an issue except for tight loop hooks that hook
into scanner.next(), etc.

+1 on committing with this check in place.

> all the methods of MasterCoprocessorHost and RegionCoprocessorHost are copy-paste, and
a couple of them have some missing fixes.
> The body of each function is the same, the only difference is the call to the specific
coprocessor.
