Olga Natkovich updated PIG-1244:

Fix Version/s: (was: 0.10)
parameter syntax in scripts, add support for ${VAR} (in addition to current $VAR)

Key: PIG-1244
Project: Pig
Issue Type: Improvement
Components: impl
Environment: all
Reporter: Alejandro Abdelnur
Assignee: Xuefu Zhang
Priority: Minor

Currently parameter syntax in pig scripts is $VAR.
This complicates scripts as parameter-literal concatenation is not supported. For example:
An occurrence of '$OUT_tmp' in a script resolves to a parameter 'OUT_tmp', it would be desirable this to resolve to a contactenation of $OUT&_tmp
This can be solved by supporting parameter syntax ${VAR}, so the pig parser can identify the end of the parameter name.
Adding support for ${VAR} syntax in addition of $VAR would maintain backwards compatibility. Changing to syntax ${VAR} syntax will break backwards compatibility.
