Turning metron core work with Model As a Service

Turning metron core work with Model As a Service


Dear all,

I completely build apache metron cluster with MaaS instance. When I test my Metron system, I encounter with problem as below:

- When I don't use MaaS, my Metron system can handle a lot of messages in high speed.

- When I use MaaS, Metron system stuck after some minutes while handle a lot of message. Logs which I receive:

org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member. This means that the time between subsequent calls to poll() was longer than the configured, which typically implies that the poll loop is spending too much time message processing. You can address this either by increasing the session timeout or by reducing the maximum size of batches returned in poll() with max.poll.records

Anybody please help me to solve this problem. Thanks a lot.
