I want to apply filter based on a list of values in Spark. This is how I get
the list:
DataFrame df = sqlContext.read().json("../sample.json");
df.groupBy("token").count().show();
Tokens = df.select("token").collect();
for(int i = 0; i < Tokens.length; i++){
System.out.println(Tokens[i].get(0)); // Need to apply filter
for Token[i].get(0)
}
Rdd on which I want apply filter is this:
JavaRDD<String> file = context.textFile(args[0]);
I figured out a way to filter in java:
private static final Function<String, Boolean> Filter =
new Function<String, Boolean>() {
@Override
public Boolean call(String s) {
return s.contains("Set");
}
};
How do I go about it?
