karthickthavasiraj09 updated KAFKA-19238:
-----------------------------------------
Description: (was: We had an issue while reading data from the Azure
Event hubs through Azure Databricks. After working with Microsoft team they
confirmed that there's an issue from Kafka side. I'm sharing the debug logs
shared by the Microsoft team below,
That took 49m, we see that task 143 takes 46 mins _(out of the job duration of_
_49m 30s)_

And this task is waiting for Kafka to respond for most of the time as we can
see from the threads:
