Pham Huy Hoang commented on KAFKA-8120:
---------------------------------------
Hi [~wj1918], I tried to test as your above steps. However, I got an
unfathomable consumer error. When I added "batch.size=1" in
config/connect-file-source.properties, my console-consumer received only
19999985 / 20000000 records (with records gen from your mongodump script), as
well as it received only 96/100 records (with your test.txt file). Sometimes,
it received only 1 records for each restarting kafka-connect. Please tell me
why.
Many thanks.
