Hi Alex,
I've posted an answer for you on Stack Overflow - I'm pasting it below, so if
anyone wants to offer any corrections, here or there, please do:
I think you need to use Twitter's Elephant Bird to parse a single json column
in Pig. (If you wanted to parse files that are json-only, you could simply use
Pig's JsonLoader API).
Here is a related question - it looks like your json is also an array, so
what's written there will apply for you, too.
In case that doesn't work, here's a blog post describing how to write a Python
UDF for a more specific case of JSON parsing. You can of course do the same
thing with a Java UDF.
Regards,Eyal
