Julien Le Dem commented on PIG-1827:
------------------------------------
After discussing with Richard and looking into the code of PreprocessorContext
http://svn.apache.org/viewvc/pig/trunk/src/org/apache/pig/tools/parameters/PreprocessorContext.java?view=markup
There seems to be a bug here:
{code}
235 //String litVal = Matcher.quoteReplacement(val);
236 replaced_line = replaced_line.replaceFirst("\\$"+key, val);
{code}
the replacement (2nd) parameter of replaceFirst is not a plain string, it can
contain references to the matched pattern like "$0" so $ in val must be escaped.
Does someone know why line 235 is commented out ?
> When passing a parameter to Pig, if the value contains $ it has to be escaped
> for no apparent reason
