Venkatesh Sivasubramanian commented on FLUME-1819:
--------------------------------------------------
Hari: In the review board, when I try to upload the git diff, I am getting a
message "No valid separator after the filename was found in the diff header".
Do you know how I can resolve that? For now, I have uploaded the Patch as an
attachment to the request (Review Request #10632).
Btw, I used "git format-patch trunk --no-prefix --stdout > FLUME-1819.patch" to
generate the Patch.
Thanks

> ExecSource has a default batchSize: 20, exec source read data from the
> source, then put it into the cache, after the cache is full, push it to the
> channel.
> but if exec source's cache is not full, and there isn't any input for a long
> time, then these entries always kept in the cache, there is no chance to the
> channel until the source's cache is full.
> so, the patch added a new config line: batchTimeout for ExecSource, and
> default is 3 seconds, if batchTimeout exceeded, push all cached data to the
> channel even the cache is not full.
