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.
> collector gets stuck when unable to write to hdfs

> Key: CHUKWA-303
> URL: https://issues.apache.org/jira/browse/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.
