[hadoop] Store GeoJson using PIG

How can I store GeoJson using PIG?

I tried to use TOBAG(lon, lat), however I got in the location stored in the
following form:

location: [
{
0: 23.80323889
}
{
0: 44.31903611
}
]

Can you post your Pig script and your index mapping? Note that for non-native types (Pig doesn't support IP or geo) you
should define the mapping in advanced in ES since es-hadoop will map it as strings as otherwise.

Index mapping (defined before running the PIG script):

curl -XPOST localhost:9200/location -d '{
"mappings" : {
"cell" : {
"properties" : {
"mapLocation" : {"type" : "geo_point" },
"name" : {"type" : "string"}
}
}
}
}'

PIG script:

location = load '/user/root/locations/cells_location.txt' USING
PigStorage('|') as (name: chararray, latitude: double, longitude: double);
locationToStore = FOREACH location GENERATE name, TOBAG(longitude,
latitude) as mapLocation;
STORE locationToStore INTO 'location/cell' USING
org.elasticsearch.hadoop.pig.EsStorage();

For the last test I used elasticsearch-hadoop-1.3.0.M2.jar

Thanks!
