Review request for Flume.
Changes
-------
address first branch requests
Bugs: FLUME-2918
https://issues.apache.org/jira/browse/FLUME-2918
Repository: flume-git
Description
-------
The way TailDir source checks which files should be tracked was improved.
Existing implementation caused unneccessary high CPU usage for huge (+50K
files) directories. This fix allows users to eliminate continous listing of
parent directory (on each Source.process invocation) and introduce a more
performant method for listing&matching files.
used java.nio.file.DirectoryStream to filter files
made pattern match calculation optionally cached
added junit tests
added javadoc
added license
