> When the "hive.server2.transport.mode" is set tp "http" (instead of "binary")
> inside the "spark2-hive-site-override" configuration then the "Spark2 Thrift
> Server" start operation fails via Ambari UI with the following error:

> This is because the "spark_service.py" script is not appending the
> "httpPath=cliservice" when the "hive.server2.transport.mode" is set to "http"
> in the "beeline_url" inside the
> "/var/lib/ambari-server/resources/stacks/HDP/3.0/services/SPARK2/package/scripts/spark_service.py"
> script (On Ambari Agent
> "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/SPARK2/package/scripts/spark_service.py").
> *Manual Workaround:*
> Update the
> "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/SPARK2/package/scripts/spark_service.py"
> on agent and amabri server as following with additional If else block to
> check the spark_transport_mode == 'http':
