Ari Rabkin updated CHUKWA-487:
------------------------------

    Priority: Blocker  (was: Major)

Also, this is a big enough problem for reliability that it should block any 0.5.

> When the name node returns errors to the collector, at some point the collector dies half way. This behavior should be changed to either resemble the agents and keep trying, or to completely shutdown. Instead, what I'm seeing is that the collector logs that it's shutting down, and the var/pidDir/Collector.pid file gets removed, but the collector continues to run, albeit not handling new data. Instead, this log entry is repeated ad infinitum:
> 2010-05-06 17:35:06,375 INFO Timer-1 root - stats:ServletCollector,numberHTTPConnection:0,numberchunks:0
> 2010-05-06 17:36:06,379 INFO Timer-1 root - stats:ServletCollector,numberHTTPConnection:0,numberchunks:0
> 2010-05-06 17:37:06,384 INFO Timer-1 root - stats:ServletCollector,numberHTTPConnection:0,numberchunks:0
