andversion
as for all otherkafka*

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
- None.
