Can you guys help me understand difference between emitted, transferred and acked tuples.
In my case every tuple emitted by ablog-filter-bolt will be processed by ablog-flatten-xml-bolt which will then be written by ablog-hdfs-bolt to hdfs. Ideally all metrics for executed/acked should match after tuples are emitted from ablog-filter-bolt . I'm not sure why there is so much discrepancy in emitted/transferredacked tuple count between these bolts although it dosent show any failed tuples.
Any ideas what I can check and how to interpret metrics correctly?
