Richard Ding commented on PIG-1819:
-----------------------------------
We're using Pig's parameter substitution parser to bind variables to the
parameters (which are marked by $). The parser doesn't allow $ in the variable
values (resulting in a parser exception). Basically, you can't substitute a
$param with a $var.
> For implicit binding, Jython embedded Pig should skip any variable/value that
> contains $.
