Subject [jira] [Commented] (HBASE-5053) HCM Tests leaks connections
Date Fri, 16 Dec 2011 18:48:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13171127#comment-13171127

nkeywal commented on HBASE-5053:

I will update the patch. For the new log line, it can happen today, so it seems better to
put it as a warning? The application will not stop from working, at least not immediately...

> There are simple leaks and one more complex.
> The complex one comes from the fact fact HConnectionManager.HConnectionImplementation
keeps a *reference* to the configuration used for the creation. So if this configuration is
updated later, the HConnectionKey created initially will differ from the current one. As a
consequence, the close() will not find the connection anymore in the list, and the connection
won't be deleted.
> I added a warning when a close does not find the connection in the list; but I wonder
if we should not copy the HConnectionKey instead of keeping a reference.
