Fengdong Yu updated FLUME-1819:
-------------------------------
Description:
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.
