Support for Hive metastore gRPC

[sumanth-manchala]

Question

Does pyiceberg supports Hive metastore exposed over gRPC instead of thrift? we are planning to use GCP's Dataproc metastore as Iceberg's catalog and would like to know the support of gRPC

i believe we only have thrift client implemented, not grpc

iceberg-python/pyiceberg/catalog/hive.py

	url_parts = urlparse(self._uri)
	socket = TSocket.TSocket(url_parts.hostname, url_parts.port)
	if not self._kerberos_auth:
	self._transport = TTransport.TBufferedTransport(socket)
	else:
	self._transport = TTransport.TSaslClientTransport(socket, host=url_parts.hostname, service="hive")
	protocol = TBinaryProtocol.TBinaryProtocol(self._transport)
	self._client = Client(protocol)
