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

Eric Yang commented on CHUKWA-303:
----------------------------------

CHUKWA-291, CHUKWA-287 are definitely not the cause of this problem.  CHUKWA-259 is not likely
the cause of this problem neither.

> 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.
