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.
