Venkatesh Seetharam commented on FALCON-697:
--------------------------------------------

bq. In eviction, we send 1 message for every path deleted to user topic. We can send 1 message with list of paths instead.
Nope. Its one message sent for all instances with a path to the instances.csv on hdfs.

bq. I guess this applies to replication and process as well
Nope. Its for an instance.

bq. In eviction, we don't send any jms message to falcon topic. Some listeners may be interested in this as well
We do and [~shaik.idris] added this in 0.5. org.apache.falcon.oozie.feed.FeedRetentionWorkflowBuilder#build
