Hi Team,
can please some body help me out what am doing wrong to get the below
exception while running my app on Yarn cluster with spark 1.4.
Kafka stream am getting AND DOING foreachRDD and giving it to new thread for
process.please find the below code snippet.
JavaDStream<MessageAndMetadata> unionStreams = ReceiverLauncher.launch(
jsc, props, numberOfReceivers,
StorageLevel.MEMORY_ONLY());
unionStreams
.foreachRDD(new
Function2<JavaRDD<MessageAndMetadata>, Time, Void>()
{
@Override
public Void
call(JavaRDD<MessageAndMetadata> rdd, Time time)
throws Exception {
new ThreadParam(rdd).start();
return null;
}
});
#############################
public ThreadParam(JavaRDD<MessageAndMetadata> rdd) {
this.rdd = rdd;
// this.context=context;
}
public void run(){
final List<StructField> fields = new ArrayList<StructField>();
List<String> listvalues=new ArrayList<>();
final List<String> meta=new ArrayList<>();
JavaRDD<Row> rowrdd=rdd.map(new Function<MessageAndMetadata, Row>() {
@Override
public Row call(MessageAndMetadata arg0) throws Exception {
String[] data=new
String(arg0.getPayload()).split("\\|");
int i=0;
List<StructField> fields = new ArrayList<StructField>();
List<String> listvalues=new ArrayList<>();
List<String> meta=new ArrayList<>();
for (String string : data) {
if(i>3){
if(i%2==0){
fields.add(DataTypes.createStructField(string, DataTypes.StringType,
true));
// System.out.println(splitarr[i]);
}else{
listvalues.add(string);
// System.out.println(splitarr[i]);
}
}else{
meta.add(string);
}
i++;
}int size=listvalues.size();
return
