Subject [jira] [Commented] (MAPREDUCE-3621) TestDBJob and TestDataDrivenDBInputFormat ant tests fail
Date Wed, 11 Jan 2012 17:55:40 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13184233#comment-13184233

Thomas Graves commented on MAPREDUCE-3621:

So issue is there is still a DB connection thread around and it gets into a deadlock between
the connection thread and the server shutdown in the main thread.  The Server shutdown in
the main thread gets a lock and waits (presumable for the connections to go away), the connection
itself is trying to obtain that same lock to do a print.  The connection never goes away so
the server shutdown times out.
