             Summary: Implement Taildir Source
                 Key: FLUME-2498
                 URL: https://issues.apache.org/jira/browse/FLUME-2498
             Project: Flume
          Issue Type: New Feature
          Components: Sinks+Sources
            Reporter: Satoshi Iijima


This is the proposal of implementing a new tailing source.
This source watches the specified files, and tails them in nearly real-time 
once appends are detected to these files.

* This source is reliable and will not miss data even when the tailing files 
rotate.
* It periodically writes the last read position of each file in a position file 
using the JSON format.
* If Flume is stopped or down for some reason, it can restart tailing from the 
position written on the existing position file.
* It can add event headers to each tailing file group. 

A attached patch includes a config documentation of this.
