Richard Ding commented on PIG-3608:
-----------------------------------
Thanks for reviewing the patch.
Right now I don't have a Pig script to demonstrate this use case. I'm getting
this problem while trying to iterate an instance of AvroMapWrapper and find out
that I can't look up the value from the map using the key just retrieved from
the map. I think this breaks the basic contract of a map implementation.
I think the check
{code}
if (isUtf8key && !(key instanceof Utf8))
{code}
is more general. But I'm ok if it is restricted to String.
