Known Issues and Limitations

  • The JDBC driver for Microsoft SQL Server does not support WITH CTE query on Spark.

  • When you enable the SSL in a mixed (FIPS and non-FIPS) configuration, Spark application run fails. To run Spark applications, set spark.ssl.ui.enabled option to false in spark-defaults.conf configuration file.

  • If you are using Spark SQL with Derby database without Hive or Hive Metastore installation, you will see the Java Runtime Exception. See Apache Spark Feature Support for workaround. Spark 3.2.0 does not support log4j1.2 logging on MapR Data Platform.

  • MapR Data Platform does not support GPU aware scheduling feature on Spark 3.2.0. See Apache Spark Feature Support.

Resolved Issues

  • None.
