-----------------------------------
Summary: With YARN, JavaSparkContext provide to add
preferredNodeLocalityData to SparkContext
Key: SPARK-4534
URL: https://issues.apache.org/jira/browse/SPARK-4534
Project: Spark
Issue Type: Improvement
Components: Java API
Reporter: Lianhui Wang
example:
SparkConf sparkConf=new SparkConf();
Configuration conf = new Configuration();
List inputFormatInfoList =new ArrayList<InputFormatInfo>();
inputFormatInfoList.add(new InputFormatInfo(conf,
org.apache.hadoop.mapred.TextInputFormat.class, path));
