Subject [jira] [Commented] (HBASE-3850) Log more details when a scanner lease expires
Date Sat, 04 Feb 2012 07:31:53 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3850?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13200358#comment-13200358

Benoit Sigoure commented on HBASE-3850:
---------------------------------------

Please respect the coding style and add the missing space after the {{else}} in the 2nd hunk
of the patch.

I wish we could get the ip:port of the client, but this patch is already a bit of an improvement,
so let's commit it.

> The message logged by the RegionServer when a Scanner lease expires isn't as useful as
it could be.  {{Scanner 4765412385779771089 lease expired}} - most clients don't log their
scanner ID, so it's really hard to figure out what was going on.  I think it would be useful
to at least log the name of the region on which the Scanner was open, and it would be great
to have the ip:port of the client that had that lease too.
