Subject [jira] [Commented] (HBASE-11516) Track time spent in executing coprocessors in each region.
Date Tue, 15 Jul 2014 17:31:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14062364#comment-14062364

Andrew Purtell commented on HBASE-11516:
----------------------------------------

I like the idea but not the proposed changes.

Suggestions

1) Expose this as a metric instead of changes to ClusterStatus. 

or

2) When changing ClusterStatus make it easy to add more metrics like this over time, something
like:

{noformat}
repeated Metric metrics = 16;

message Metric {
    required string name = 1;
    required uint64 value = 2;
}
{noformat}

I'd prefer option 1. I don't think we should be passing metrics through ClusterStatus. However,
if consensus opinion is we can and should do that here, then I prefer option 2 over the current
patch.

can be handy for debugging coprocessors in case of any trouble.
