Hello @AdityaShaw ,   sorry I have missed addressing your enquiry about the server 500 error. Based on the KB article you referenced, it is related to the bug. Do you still have the server 500 error once hive.server2.thrift.http.cookie.auth.enabled is set to false, please?   Should you experience disconnects even after applying the workaround, you might have too many HTTPClient connections, which are too high for KNOX to handle at a time.   Please only change any of the parameters listed below once you tested that the above workaround was not sufficient. Based on my research the below parameters are still safe to apply. Before applying any changes in production, please test out the new values in a non-prod environment, as we are not familiar with your use cases and how your cluster/workload is designed: gateway.httpclient.connectionTimeout=600000 (10 min) gateway.httpclient.socketTimeout=600000 (10 min) gateway.metrics.enabled=false gateway.jmx.metrics.reporting.enabled=false gateway.httpclient.maxConnections=128   Kind regards: Ferenc   ...

(Have not tested it, so feel free to browse in this topic).   Once you know what is the character encoding for the source data, please set your "Character Set" in NiFi accordingly.   Please let us know if it helped by pressing the "Accept as Solution" button.   Kind regards: Ferenc ...
