----------------------------------

Sorry I meant to say, jetty has been shutdown, but the java vm didn't exit cleanly.

> The recent change to collector may have problems.  Last night, I shutdown hdfs, and expecting the collectors to bail out by themselves, and restart by the watchdog.  However, this morning, the collector was still running and sending 0 bytes to the system.  Port 4080 isn't accepting any more HTTP post.  This indicates that the jettyCollector may have been shutdown but the java program didn't exist.  The only change to collector is the LocalWriter enhancement, and it isn't enabled.
