----------------------------------
I believe the class is new in 1.2. You are looking at the example code as of
master, but the class documentaiton as of 1.1.
> JavaNetworkWordCount.java has a wrong import

> JavaNetworkWordCount.java has a wrong import.

> [Duration|https://spark.apache.org/docs/latest/api/java/org/apache/spark/streaming/Duration.html]
> (or
> [Seconds|https://spark.apache.org/docs/latest/api/java/org/apache/spark/streaming/Seconds.html]),
> not **Durations** .
> Also [line
> 60|https://github.com/apache/spark/blob/master/examples/src/main/java/org/apache/spark/examples/streaming/JavaNetworkWordCount.java#L60]
> should change accordingly because currently it reads as:
> {code:title=JavaNetworkWordCount.java|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
> JavaStreamingContext ssc = new JavaStreamingContext(sparkConf,
> Durations.seconds(1));
> {code}
