> Would be possible for someone to modify JsonStorage.java to also implement FileInputLoadFunc
? e.g. atleast to be able to load .json documents which were stored with PigStorage or use
the same json structure?
> -- store JsonStorage() test
> a = load '/jsonStorage1.txt' as (a0:int, a1:{t:(a10:int, a11:chararray)},a2:(a20:double,
a21), a3:map[chararray]);
> store a into '/jsonStorage1.json' using JsonStorage();
> -- load JsonStorage() test
> b = load '/jsonStorage1.json' using JsonStorage();
> descbibe a; -- both a and b have same schema but b got its schema from the json meta
> describe b;
