Purpose

Indicates which protocol to use when connecting to the Apache Hive server.

Valid Values

auto | HiveServer1 | HiveServer2

Behavior

If set to auto, the driver tries to connect using the HiveServer1 protocol and the HiveServer2 protocol simultaneously. Whichever server socket accepts the connection is the one that the driver continues to use for subsequent connections. For example, if the server socket accepts a connection request using the HiveServer2 protocol, subsequent connections from the driver use the same socket and protocol.

If set to HiveServer1, the driver only uses the HiveServer1 protocol to communicate with the server.

If set to HiveServer2, the driver only uses the HiveServer2 protocol to communicate with the server.

Notes

  • If the protocol specified for WireProtocolVersion is not accepted by the Hive server to which you are connecting, the connection fails with a login timeout error, if LoginTimeout is enabled. For example, a login timeout error would be returned if you specify WireProtocolVersion=HiveServer2 and the driver attempts to connect to an Apache Hive server that only accepts connections using the HiveServer1 protocol.
