Harsh J commented on PIG-2837:
------------------------------
I can imagine this happening if there's a self-reference in the schema. For
example, an array of the record name itself being a field inside the schema. In
this case, the record's type and schema is re-resolved and it enters an
infinite loop.
I suppose we could keep a reference of names (with namespace, for correctness)
and only re-call if we've not already visited it?
