[jira] [Created] (FLUME-1947) ExecSource should optionally block if the channel is full.

Hari Shreedharan created FLUME-1947:
---------------------------------------

             Summary: ExecSource should optionally block if the channel is full.
                 Key: FLUME-1947
                 URL: https://issues.apache.org/jira/browse/FLUME-1947
             Project: Flume
          Issue Type: Bug
            Reporter: Hari Shreedharan


This is so that the process executed blocks till the channel clears up. This is exceptionally useful if the process is a tail -F or something like that. 

In addition, the exec source does have issues with respect to the last batch not being sent. We could also specify a timeout at the end of which the batch should be flushed to the channel if there are no new events.
