[jira] Created: (CHUKWA-159) Unregister incorrect adaptor ID
Unregister incorrect adaptor ID
-------------------------------
Key: CHUKWA-159
URL: https://issues.apache.org/jira/browse/CHUKWA-159
Project: Hadoop Chukwa
Issue Type: Bug
Components: data collection
Environment: Redhat EL 5.1, Java 6
Reporter: Eric Yang
Priority: Blocker
Two of the long running clusters show the same symptoms, where jvm and namenode metrics files are unregistered when they shouldn't. This may not be the same issue as CHUKWA-5. However, someone should take a closer look at the problem associate with ChukwaAgent and ChukwaAgentController.

Cheng commented on CHUKWA-159:
------------------------------
There are couple places where a metrics adaptor gets unregistered
1 Agent restart as mentioned in chukwa-5.
2 Metrics log file doesn't exist or it's not readable.
3 Race condition as mentioned by Chukwa-68
After investigation, #1 and #2 might not be the cause. I will focus on #3.
