Known Issues and Limitations

  • MAPR-28087: Livy cannot use the Hive Interpreter. Workaround: Use the cluster mode. Set livy.spark.deployMode=cluster in the ${LIVY_CONF}/livy.conf file. This issue is caused by Spark 11851 - Unable to start Spark thrift server against secured hive metastore (GSS initiate failed).
  • LIVY-42: Livy UI is not accessible on Kerberos.
