Hello I have been working on my IBM cognos analytics on cloud dashboard and every time i load my data and drag the dataset on the dashboard i get spark error. earlier it was fine but now i get this error (screenshot attached) anytime I try to work to create some visualization. I have deleted my dataset and tried uploading again but it doesn't work. I have even tried with smaller datasets but still nothing different. email registered with the account - magicia9n@gmail.com. It is a cloud trial for cognos analytics and I am using it to finish my coursera course.

This is the error i am getting:

XQE-DAT-0001 Data source adapter error: GeneralException(requestId:c8fae4d5-0316-4098-9b61-0b4bd9d72d4c, message:Cannot call methods on a stopped SparkContext. This stopped SparkContext was created at: org.apache.spark.sql.SparkSession$Builder.getOrCreate(SparkSession.scala:1093) com.ibm.ba.flint.server.FlintServer.startSpark(FlintServer.java:699) com.ibm.ba.flint.server.FlintServer.startUp(FlintServer.java:609) com.ibm.ba.flint.server.FlintServer.run(FlintServer.java:338) com.ibm.ba.flint.server.FlintServerApp.runServer(FlintServerApp.java:304) com.ibm.ba.flint.server.FlintServerApp.main(FlintServerApp.java:236) The currently active SparkContext was created at: (No active SparkContext.) , trace:java.lang.IllegalStateException

any idea how to fix this?

Hi Apurva,

Did you try to use the data from Samples? How large is your dataset?

In your CSV file, I see that you have only 4 columns. You should try to use Samples data, you'll have many columns, and it will be easier to create a dashboard.

Best regards,
