import org.apache.hadoop.net.NetUtils; //導入方法依賴的package包/類
/**
* Create a new NuCypherExtClient connected to the given nameNodeUri or rpcNamenode.
* If HA is enabled and a positive value is set for
* {@link HdfsClientConfigKeys#DFS_CLIENT_TEST_DROP_NAMENODE_RESPONSE_NUM_KEY}
* in the configuration, the DFSClient will use
* {@link LossyRetryInvocationHandler} as its RetryInvocationHandler.
* Otherwise one of nameNodeUri or rpcNamenode must be null.
