> 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
