subdirectory - Flume "Spooling Directory Source" recursive-look for the the files within subdirectories -

i looking flume "spooling directory source" recursive-look the files within subdirectories. there references here https://issues.apache.org/jira/browse/flume-1899 since multiple versions have come out, there way can have recursive directory lookup within subdirectories files in spooling source.

i think can use patch flume-1899-2.patch directly. set "recursivedirectorysearch" ture in config file.

note: regex in ignorepattern of config file affect recursivedirectory folder name. might need modify code in org/apache/flume/client/avro/reliablespoolingfileeventreader.java if want ignore folder name.
