I am using the ElasticSearch for Hadoop library defined in  
"[http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/pig.html](http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/pig.html)"  
to read data in PIG for Hadoop.

There is a field "household\_ages" defined as "short" in my index type. But  
it is actually an array since this field has multiple values.  
PUT /myindex/mytype/\_mapping  
{  
"mytype": {  
"properties": {  
...  
"household\_ages": {"type": "short"}  
}  
}  
}

An example value of the field "household\_ages" is like: [45,40,17,13]

When I run the PIG script, the script can't read the value of the field  
"household\_ages", other fields with the primitive type, or map type are  
fine. Only the field with array of primitive can't be read correctly.

Below is the PIG script:  
A = LOAD 'myindex/mytype' USING  
org.elasticsearch.hadoop.pig.EsStorage('es.nodes=localhost:9200');  
DUMP A;

The value I got for this column is "(,,,)".

Below is a complete record dumped by PIG script. I can see values are read  
properly for other fields. Only the "household\_ages" field can't get the  
data:  
(12345,[lname#Smith,fname#John],[state# NY,zip# 00000,city#New  
York,street#123 Main  
St],(,,,),[special\_clearance#true,weekly\_update#true,birthday\_greeting#false])

Does any one have any idea how to fix the issue?

Thanks,  
Juan
