Dear Team,
I am facing one error while trying to create a table in dremio using JDBC driver, invoked via Spark.
I am trying to create a table. The query is visible for almost 3 minutes in the jobs link. But later reports that it was cancelled. Below is the error that I am seeing in the Spark job.

But when I try to execute this using spark-shell via dremio JDBC, there is no issue.
Can you please throw some light on this?
