Known Issues and Limitations

  • KAFKA-848: If used with Core 6.2, Kafka services will not start because of:
    java.lang.ClassNotFoundException: org.bouncycastle.jsse.provider.BouncyCastleJsseProvider
    To work around this exception, copy the bc-fips and bctls-fips jars from Hadoop to Kafka manually:
    cp /opt/mapr/hadoop/hadoop-2.7.6/share/hadoop/common/lib/bctls-fips-1.0.11.4.jar /opt/mapr/kafka/kafka-2.6.1/libs/  
    cp /opt/mapr/hadoop/hadoop-2.7.6/share/hadoop/common/lib/bc-fips-1.0.2.1.jar /opt/mapr/kafka/kafka-2.6.1/libs/
  • 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.
