Hi ,
I have configured the Cygnus instance with the following configuration for Hive:

cygnus-ngsi.sinks.hdfs-sink.hive.host = cosmos.lab.fiware.org
cygnus-ngsi.sinks.hdfs-sink.hive.server_version = 2
cygnus-ngsi.sinks.hdfs-sink.file_format = json-column
cygnus-ngsi.sinks.hdfs-sink.csv_separator = ,
cygnus-ngsi.sinks.hdfs-sink.hdfs_host = storage.cosmos.lab.fiware.org
cygnus-ngsi.sinks.hdfs-sink.hdfs_port = 14000
cygnus-ngsi.sinks.hdfs-sink.hdfs_username = <username>
cygnus-ngsi.sinks.hdfs-sink.hdfs_password = <password>
cygnus-ngsi.sinks.hdfs-sink.oauth2_token = <token>
cygnus-ngsi.sinks.hdfs-sink.hive = true

After table creation, I have received the below error message:

Error message:

I solved the issue regarding the error message using this link:

https://community.cloudera.com/t5/Batch-SQL-Apache-Hive/Where-to-put-json-serde-1-3-7-jar-with-dependencies-jar-file/td-p/48073<http://cp.mcafee.com/d/avndygsd3gOrhvKYY-U-NsTsSyyPtBBBVBMSyyOyevKUYyrhhp76zBWXVEVd79J55VNdNZcQszzrItxrWmHOSHr7PPZ1lGNcWuvaDiCrJm9DjPVkWkPuE9LK-qen-LOrz1EVd7bPTnKnjpujVxUsUOUVR4mlHFGTppVkffGhBrwqrhdI6XYCyOzsQsIL8I6XCOsVHkiP5RmUiCmWNZmQfzLbVd_1DpS9BNw1MGn45JIjYK5V6vM1ivNYLeFtpKpshFm1uDNgYKynpbzyUzIiVykOpt3RLwxYbi-xshS9tSh_Vd0KJz3RNP9IhHjV4orqluJIo_fUR1jIz6N_w09JAsYYyCr1vF6y0bOc-q82VEw0woH0o-a7Cy0-h2eNb6y0Kq818IhwTgSOedBjl2gIAwSd_>

and after that I have tried to deploy on my local Hive istance the jar library recovered by http://www.congiu.net/hive-json-serde/<http://cp.mcafee.com/d/FZsS93gwrhvKYY-U-NsTsSyyPtBBBVBMSyyOyevKUYyrhhp76zBWXVEVd79J55VNdNZcQszzrItxrWmHOSHr7PPZ1lGNcWuvaDiCrJm9DjPVkWkPuE9LK-qen-LOrz1EVd7bPTnKnjpujVxUsUOUVR4mlHFGTppVkffGhBrwqrjdI6XYCyOzsQsIL8I6XCM0lGM8OrU6UjApYK8QH0LjUEvxIhHjV4orqluJIo_fUR1jIz6N_w09JAsYYyCr1vF6y0bOc-q82VEw0woH0o-a7Cy0-h2eNb6y0Kq818IhwTgSOedFPnyNnzG> (version 1.3.8)
and now It's correctly working in local.
