Richard Ding commented on PIG-1827:
-----------------------------------
Looked into it a little more. Actually, embedded Pig just use parameter
substitution to perform parameter binding and it doesn't support recursive
substitution. So it should be ok to remove the requirement that $ in parameter
be escaped.
> When passing a parameter to Pig, if the value contains $ it has to be escaped
> for no apparent reason
