Santhosh Srinivasan commented on PIG-893:
-----------------------------------------
What are the semantics of chararray (string) to numeric types?
Pig does not support conversion of any non-bytearray type to bytearray. The
proposal in the jira description is minimalistic. Does it match with that of
SQL?
Without clear articulation about what these things mean, we cannot/should not
support chararray to numeric type conversions. PiggyBank already supports UDFs
that convert strings to int, double, etc.
It's a nice to have, as part of the language but its better positioned as a
UDF. If clear semantics are laid out then making it part of the language will
be a matter of consensus.
> support cast of chararray to other simple types
