Issue while reading data from Kafka topic to Spark strutured streaming

ramravi — Tue, 03 Jan 2023 09:19:32 GMT

py4j.security.Py4JSecurityException: Method public org.apache.spark.sql.streaming.DataStreamReader org.apache.spark.sql.SQLContext.readStream() is not whitelisted on class class org.apache.spark.sql.SQLContext

I already disable acl for cluster using

"spark.databricks.acl.dfAclsEnabled":true at cluster configuration.

Also Table access control disables for workspace.

I followed this link but not helping

Don't you have some policies set by the administrator?

Additionally, when starting the cluster, please choose "Access mode" = "Single user".

Hi @Ravi Teja,

Just a friendly follow-up. Do you still need help? if you do, please share more details, like DBR version, standard or High concurrency cluster? etc

Hi, Streaming is not supported in credentials passthrough, table ACLS or HC clusters, which is not the case here as you mentioned those options are already disabled. Could you please crosscheck and raise a support case with Databricks if everything looks fine from your end?
