Attribute

TransportMode (TRM)

Purpose

Specifies whether binary (TCP) mode or HTTP mode is used to access Apache Spark SQL data sources.

Valid Values

0 | 1

Behavior

If set to 0 (binary), Thrift RPC requests are sent directly to data sources using a binary connection (TCP mode).

If set to 1 (HTTP), Thrift RPC requests are sent using HTTP transport (HTTP mode). HTTP mode is typically used when connecting to a proxy server, such as a gateway, for improved security, or a load balancer.

Notes

  • The setting of this option corresponds to that of the hive.server2.transport.mode property in your hive-site.xml file.
  • When HTTP mode is enabled (TransportMode=1), the HTTP/HTTPS end point for the Hive server must be specified using the HTTP Path option.
  • To configure the driver to use HTTPS end points, set TransportMode=1 (HTTP) and EncryptionMethod=1 (SSL).
  • If connecting to an Azure Databricks Spark cluster, this option must be set to 1 (HTTP).

Default

0 (binary)
