@Deepak_Unravel  This is a regression on the python3 upgrade or more specifically something that worked by mistake in the past. Before py3 avro used to be more flexible with it's schema's and used to ignore any extra fields. If a value didn't exist in the schema it could have any value without invalidating the parcel. Now it expects data to be in exact format to the schema which is more accurate. During the py3 migration most fields were added but looks like we missed the conflicts field. A workaround for now can be to remove the conflicts field from the parcel since it doesn't have any conflicts right now. Please remove the conflicts entry in /opt/cloudera/parcels/UNRAVEL_SENSOR-1.0.4791002_cdh7.1_h3.1_s2.4/meta/parcel.json file on all the agents. Post conflicts entry removal you will able to distribute the parcel. ... View more
