Subject [jira] [Commented] (HDFS-2213) DataNode gets stuck while shutting down minicluster
Date Tue, 02 Aug 2011 14:47:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13076236#comment-13076236

Todd Lipcon commented on HDFS-2213:

my question is what changed in trunk in the last couple of weeks that made this start happening
with high frequency. I had never seen it before about a month ago, and now I see it most days.

> I've seen a couple times where a unit test has timed out. jstacking shows the cluster
is stuck trying to shut down one of the DataNode HTTP servers. The DataNodeBlockScanner thread
also seems to be in a tight loop in its main loop.
