Reading json file.

[jamal sasha]

Hi,

I have json file in follwoing format:
{ "_id" : "foo.com", "categories" : [], "h1" : { "bar==" : { "first" :
1281916800, "last" : 1316995200 }, "foo==" : { "first" : 1281916800, "last"
: 1316995200 } }, "name2" : [ "foobarl.com", "foobar2.com" ], "rep" : null }
So, how do i parse this json in pig..

also, the categories and rep can have some char in it..and might not be
always empty.

Thanks
