RPC server's SASL_PROPS shouldn't be re-initialized every time an RPC client is
created
---------------------------------------------------------------------------------------
Key: HADOOP-6902
URL: https://issues.apache.org/jira/browse/HADOOP-6902
Project: Hadoop Common
Issue Type: Bug
Components: ipc, security
Reporter: Kan Zhang
SaslRpcServer.SASL_PROPS is a SASL server property and should stay constant
after initialization. In the initial implementation, we assumed all SASL
clients will use the same constant value. If different clients might use
different values depending on the conf in the getProxy() call (as current code
implies), each client should have its own copy. In any case, a client shouldn't
re-initialize server's copy.
