Russell Jurney resolved PIG-2440.
---------------------------------
Resolution: Invalid
I need to play with AvroStorage more to better characterize this bug before
reporting. Sometimes it works, sometimes it does not.
> AvroStorage won't store :(

> I am creating Avro records according to the instructions/code at
> https://github.com/rjurney/Collecting-Data They look like this:
> {
> "namespace": "agile.data.avro",
> "name": "Email",
> "type": "record",
> "fields": [
> {"name":"message_id", "type": ["string", "null"]},
> {"name":"from","type": ["string", "null"]},
> {"name":"to","type": [{"type":"array", "items":"string"},
> "null"]},
> {"name":"cc","type": [{"type":"array", "items":"string"},
> "null"]},
> {"name":"bcc","type": [{"type":"array", "items":"string"},
> "null"]},
> {"name":"reply_to", "type": [{"type":"array", "items":"string"},

> {"name":"subject", "type": ["string", "null"]},
> {"name":"body", "type": ["string", "null"]},
> {"name":"date", "type": ["string", "null"]}
> ]
> }
> I have applied the patch at PIG-2411 to get Pig to store bags in Avro arrays.
