[jira] [Created] (PIG-2758) Incomplete implementation in pig
Mridul Muralidharan created PIG-2758:
----------------------------------------
Summary: Incomplete implementation in pig
Key: PIG-2758
URL: https://issues.apache.org/jira/browse/PIG-2758
Project: Pig
Issue Type: Bug
Environment: All env
Reporter: Mridul Muralidharan
Support for Map's is not consistent in the builtin evalfunc/impl. There might be other inconsistencies too (like BIGCHARARRAY, but I have not investigated).
For example: search for Long.class or Long.TYPE - this gives us the list of classes/usecases where "Map" is not supported the same way .. Invoker, MonitoredUDFExecutor.
This is NOT a principled way to find all instances of this sort of buggy behavior - someone with better knowledge of pig internals (DataType's, other langs, checks, etc) can do a better job.

----------------------------------------
The two cases you called out are specifically documented as not supporting complex types.
