+ * Counts words in text encoded with UTF8 received from the network every
second.

+ * Usage: JavaRecoverableNetworkWordCount <hostname> <port>
<checkpoint-directory> <output-file>
+ * <hostname> and <port> describe the TCP server that Spark Streaming
would connect to receive
+ * data. <checkpoint-directory> directory to HDFS-compatible file system
which checkpoint data
+ * <output-file> file to which the word counts will be appended
+ *
+ * <checkpoint-directory> and <output-file> must be absolute paths
+ *
+ * To run this on your local machine, you need to first run a Netcat server
+ *
+ * `$ nc -lk 9999`
+ *
+ * and run the example as
+ *
+ * `$ ./bin/run-example
org.apache.spark.examples.streaming.JavaRecoverableNetworkWordCount \
+ * localhost 9999 ~/checkpoint/ ~/out`
+ *
+ * If the directory ~/checkpoint/ does not exist (e.g. running for the
first time), it will create
+ * a new StreamingContext (will print "Creating new context" to the
console). Otherwise, if
+ * checkpoint data exists in ~/checkpoint/, then it will create
StreamingContext from
+ * the checkpoint data.

+ * To run this example in a local standalone cluster with automatic driver
recovery,

Can you remove this reference to spark standalone cluster mode? These
instructions are old and irrelevant. Please remove from both examples :)
