Subject [jira] Created: (CHUKWA-303) collector gets stuck when unable to write to hdfs

collector gets stuck when unable to write to hdfs

                 Key: CHUKWA-303
             Project: Hadoop Chukwa
          Issue Type: Bug
          Components: data collection
    Affects Versions: 0.2.0
            Reporter: Eric Yang
            Priority: Blocker
             Fix For: 0.2.0

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.
