Known Issues and Limitations
- Transactions are not supported.
- Pattern subscription is not supported.
- The application reset tool hangs if it runs when the Kafka Streams application is running.
- The application reset tool may throw a Null Pointer Exception when the date or duration parameter is used.
- The application reset tool does not reset to intermediate offset if the topic has multiple partitions.
- MAPR-KAFKA-581: Stream hangs in rebalancing state. The workaround is to set a larger timeout. This issue is caused by MS-915: “MapR Stream application hangs inside cycle”
Resolved Issues
-
[MS-1386, KAFKA-983]: Consumer client events related to consumer rebalance (assignment change,
ConsumerRebalanceListener
callbacks, invocation, etc.) now happen only inside theconsumer.poll()
method in the user thread, according to the Apache defined behavior. -
[KAFKA-1031]: In Kafka REST, this means that subscribing a consumer by sending a
POST
request to a/subscription
endpoint will not cause partitions to be assigned to it. Partitions will be assigned only on the next poll call (GET /records
).
