Geo_point field problems

[1222kkk (new to Es)]

mapping just as following:

 "properties": {
           "BH": {
              "type": "string"
           },
           "GD": {
              "type": "long"
           },
           "GJ": {
              "type": "string"
           },
           "GPS": {
              "type": "geo_point"
           },
           "HX": {
              "type": "double"
           },
           "MC": {
              "type": "string"
           },
           "MC2": {
              "type": "string"
           },
           "MC3": {
              "type": "string"
           },
           "MC4": {
              "type": "string"
           },
           "SJ": {
              "type": "date",
              "format": "yyyy/MM/dd HH:mm:ss||yyyy/MM/dd||epoch_millis"
           }
        }

the test data :

{
       "GPS":{
              "lat":21.22222,
              "lon":22.111111        
        }
}

Then use es-hadoop to cache data to Spark

if the mount of data is below 10,000, all works well.
While cache more data, Spark throw the following errors:

    17/03/07 11:18:52 ERROR Executor: Exception in task 30.0 in stage 19.0 (TID 166)
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double
        at scala.runtime.BoxesRunTime.unboxToDouble(BoxesRunTime.java:114)
        at org.apache.spark.sql.catalyst.expressions.BaseGenericInternalRow$class.getDouble(rows.scala:44)
        at org.apache.spark.sql.catalyst.expressions.GenericInternalRow.getDouble(rows.scala:221)
        at

Then I tried to update all gps fields, with array format:

{
      "GPS":[
              21.22222,
              22.111111        
        ]
}

Well, all success. Although Spark cache geo_point as array type.

Above all, I just wonder what's the correct way to cache geo_point type fields in Spark to avoid type error?

language: scala
es version: 2.3.2
es-hadoop version: 5.1
spark version:2.0.2

Thanks for your help!
