"hdfs://hdmaster:54310/user/hive/warehouse/temp/Dataformated/finalformated");
String classifyPath=Output Path;
hdfsPath = classifyPath/pmml File Name;
Tap classifyTap = new Hfs(new TextDelimited(true, "\t"),
classifyPath/pmml File Name));
String formatLocalHdfsData = classifyPath/PMML FILE NAME);
FlowDef flowDef = FlowDef.flowDef().setName("classify")
.addSource("input", inputTap)// input is LFs or HFS
.addSink("classify", classifyTap);
flowDef.addAssemblyPlanner(pmmlPlanner);
Flow classifyFlow = flowConnector.connect(flowDef);
classifyFlow.writeDOT("dot/classify.dot");
classifyFlow.complete();

Please Help Me to solve this Issue.

Answer 1

I resolve the issue. In log file I was getting serialVersionID compatibility issue. Generate the new SerialVersionID and it worked.
