Subject [jira] Created: (CHUKWA-330) controller should not create duplicates for adaptors with offsets
Date Tue, 23 Jun 2009 23:39:07 GMT
controller should not create duplicates for adaptors with offsets
-----------------------------------------------------------------

                 Key: CHUKWA-330
                 URL: https://issues.apache.org/jira/browse/CHUKWA-330
             Project: Hadoop Chukwa
          Issue Type: Bug
          Components: input tools
            Reporter: Ari Rabkin
            Assignee: Ari Rabkin
            Priority: Blocker


The offset-of-first-byte param to FileTailingAdaptor is hashed into the default adaptor name.
 This changes the semantics of adaptor uniqueness, and broke metrics and the log4jappender.

Proposed fix:
  Add a new "addByName()" method to ChukwaAgentController that lets callers specify names.
 
  Use this new method whenever finer control of adaptor uniqueness is needed.
