/**
* Counts words cumulatively in UTF8 encoded, '\n' delimited text received
from the network every
* second.
- * Usage: StatefulNetworkWordCount <master> <hostname> <port>
- * <master> is the Spark master URL. In local mode, <master> should be
'local[n]' with n > 1.
+ * Usage: StatefulNetworkWordCount <hostname> <port>
* <hostname> and <port> describe the TCP server that Spark Streaming
would connect to receive
* data.
*
* To run this on your local machine, you need to first run a Netcat server
* `$ nc -lk 9999`
* and then run the example
- * `$ ./bin/run-example
org.apache.spark.streaming.examples.StatefulNetworkWordCount local[2] localhost
9999`
+ * `$ ./bin/spark-submit examples.jar
+ * --class org.apache.spark.streaming.examples.StatefulNetworkWordCount
localhost 9999`
