A quick question on the JSON handling in PIG.
I tried some JsonLoader called Elephant-Bird to load and handle JSON data like
the followings:{
"SV":1,
"AD":[
{
"ID":"46931606",
"C1":"46",
"C2":"469",
"ST":"46931",
"PO":1
},
{
"ID":"46721489",
"C1":"46",
"C2":"467",
"ST":"46721",
"PO":5
}
]
}
The loader works well for simple fields but it doesn't work well for any array
field. I don't know how I can access elements in the array ("AD" field above)
with this UDF or in any other way? Please advise.
Thanks,-K
