Vlad Rozov updated APEXMALHAR-2557:
-----------------------------------
Description:
While using the TimeBasedDedupOperator for deduping, I see that operator
keeps failing with below NullPointer exception.
I also see that operator is always high on CPU usages. Almost reaching 100%.
No matter the setting any values for vcores or container memory for operator
