Convert a protobuf token into a rpc token and set its service. Supposed to be used for tokens other than RMDelegationToken. For RMDelegationToken, use convertFromYarn(org.apache.hadoop.yarn.api.records.Token, org.apache.hadoop.io.Text) instead.

Parameters:

protoToken - the yarn token

serviceAddr - the connect address for the service

Returns:

rpc token

Convert a protobuf token into a rpc token and set its service.

Parameters:

protoToken - the yarn token

service - the service for the token
