tailers could be more thrifty with filehandles
----------------------------------------------
Key: CHUKWA-361
URL: https://issues.apache.org/jira/browse/CHUKWA-361
Project: Hadoop Chukwa
Issue Type: Improvement
Reporter: Ari Rabkin
Right now, when a FileTailingAdaptor is watching a file, it keeps it open.
This is a scaling bottleneck. Would be nice to have a separate,
non-rotation-aware adaptor that doesn't keep the file open when it isn't
actively reading data.
