I have designed a class which basically reads parquet data and saving them as form of javaRDD into ES.

Spark Version: 1.5  
CDH Version: CDH-5.5.2-1.cdh5.5.2.p0.4

Getting the following exception during the saveToEs Stage

Below the code snippet

```
JavaRDD<Charval> Charvals = charVal_select.javaRDD().map(new Function<Row, Charval>() {
	    /**
		 * 
		 */
		private static final long serialVersionUID = 1L;

		public Charval call(Row y) throws Exception {
	    	 return Charval.builder()
	           			.charvalCode(y.getString(0))
																					.charCode(y.getString(1))
																					.charvalType(y.getString(1))
																					.numericVal(y.getDouble(2))
																					.unitOfMeasure(y.getString(3))
																					.proposalFlg(y.getString(4))
																					.intrnlUseFlg(y.getString(5))
																					.cmrclySensitiveFlg(y.getString(6))
																					.updDttmUtc(y.getTimestamp(7))
																					.descriptionAlt(DescriptionAlt.builder().dscrAltEnZz(y.getString(8)).build())
																					.descriptionMain(DescriptionMain.builder().dscrMainEnZz(y.getString(9)).build())
																					.build();
	    }
	});
	
//	JavaRDD _esCharValRDD = sc.parallelize(Arrays.asList(esCharValRDD.first()),40000);
	if(ESMainProcessor.isFullSync()){
	//	ESNativeOperations.deleteIndex(UtilityManager.getESNativeClient(), "rd_cval/cval");
	//	JavaEsSpark.saveToEs(esCharValRDD, "rd_cval/cval");
	}else{
		
	}
	
	JavaEsSpark.saveToEs(Charvals, "rd_cval/cval");

```

I took the help of Kyro serialization as well. This cluster has lot of other systems running and the spark cannot be upgraded if the solution is to upgrade. I need at least workaround. Please help  
Also tried Parallelizing, which took humongous time still failed during write to es.

I had the same [issue](http://stackoverflow.com/questions/36359709/spark-elasticsearch-hadoop-task-exception-could-not-be-deserialized) before and I think it was caused by an incorrect es-hadoop package.

What version of the es-hadoop package are you using? Can you post your spark-submit command?
