Rename/Add 'string' as a type in place of chararray - and deprecate (and
probably eventually remove) the use of 'chararray'
---------------------------------------------------------------------------------------------------------------------------
Key: PIG-912
URL: https://issues.apache.org/jira/browse/PIG-912
Project: Pig
Issue Type: Bug
Reporter: Mridul Muralidharan
The type 'chararray' in pig does not refer to an array of characters (char [])
but rather to java.lang.String
This is inconsistent and confusing naming; and additionally, will be a
interoperability issue with other systems which support schema's (zebra among
others).
It would be good to have a consistent naming across projects, while also having
appropriate names for the various types.
Since use of 'chararray' is already widely deployed, it would be good to :
a) Add a type 'string' (or equivalent) which is an alias for 'chararray'.
Additionally, it is possible to envision these too (if deemed necessary - not a
main requiremnt) :
b) Modify documentation and example scripts to use this new type.
c) Emit warnings about chararray being deprecated.
