Known Issues and Limitations

  • 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”
