Subject Re: TransactionalTridentKafkaSpout using only 1 executor
Date Thu, 04 Dec 2014 21:51:45 GMT

can you post your storm UI executors page image. If there are 16
executors but only 1 seems to have fetching data. Can you please check
on your kafka producer if its distributing your data among all of your
partitions.
