Subject Re: CDH3b3 deadlock in jobtracker
Date Thu, 16 Dec 2010 17:59:29 GMT
Replying back on common-dev list because I've determined this issue
exists upstream. Configuration.writeXml will deadlock if the XML
output is larger than one block (or I think if pipeline recovery
happens mid-write)

I filed HDFS-1542.
