I am having problems while trying to write an ES string array from my Pig  
script. The current ES-hadoop documentation (  
[http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/pig.html](http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/pig.html))  
states that a pig Bag maps to a ES Array. It sounds like you should be  
able to stick all of the items you want in the array into a bag, than when  
that bag is loaded into ES it turns into an array, but this is not working  
as expected. I am using elasticsearch-hadoop (1.3 m2), hadoop 2, and  
elasticsearch 0.90.5.

## Here is an example:

% this is pseudo grunt code here:  
% test\_data = A,B,C  
data = LOAD 'test\_data' USING PigStorage (',') AS (f1: chararray, f2: chararray, f3: chararray);  
data2 = FOREACH data GENERATE TOBAG(f1, f2, f3) AS my\_fields;  
STORE data2 INTO 'dgb-1610/test' USING EsStorage();

dump data2  
({(A),(B),(C)})

describe data2  
data2: {my\_fields: {(chararray)}}

* * *

## this is what the resulting index looks like:

curl -XGET '[http://gblb-es01.dev.g2:9200/dgb-1610/test/\_mapping](http://gblb-es01.dev.g2:9200/dgb-1610/test/_mapping)'  
{  
"test": {  
"properties": {  
"my\_fields": {  
"properties": {  
"0": {  
"type": "string"  
}  
}  
}  
}  
}  
}----------------------------------------------

## but this is how I expect it to be:

{  
"test": {  
"properties": {  
"my\_fields": {  
"type": "string"  
}  
}  
}  
}  
}
