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.
