Spark Operations

You can perform the clearSparkContext operation by using the Spark MBean.



If you have a requirement to reinitiate Apache Spark and the worker nodes and if there is no other reason to restart the TIBCO MDM server, then clear the spark context to initiate big data import. In the MBeans tab, double-click the clearSparkContext() method to clear the spark context.

From the Apache Spark application Web UI, you can verify that the running applications are cleared and added under the completed applications.

After clearing the spark context, if you initiate the big data import, the import runs successfully.
