@sandeephenkel23 I've run the same code in DBR 13.3 LTS, and 1) It is successfully imported, 2) I can confirm it is in the whitelisted libs. Hence I'm wondering if there's anything else particular in your use case, triggering this? Is your use case a simple DBR 13.3 LTS bare cluster, no additional configs, and also no additional code other than what you have shared here, not used within a UDF, or in a py environment, etc, etc? If you can provide the exact reproducer, we can get to the root cause. Please consider all possible variables, like cluster mode (Assigned, Shared, etc), policies, spark properties, etc.
