When passing a parameter to Pig, if the value contains $ it has to be escaped
because of a bug in PrecprocessorContext
----------------------------------------------------------------------------------------------------------------------
Key: PIG-2074
URL: https://issues.apache.org/jira/browse/PIG-2074
Project: Pig
Issue Type: Bug
Components: impl
Reporter: Julien Le Dem
Priority: Minor
This was raised while looking at PIG-1827
There seems to be a bug in PreprocessorContext:
http://svn.apache.org/viewvc/pig/trunk/src/org/apache/pig/tools/parameters/PreprocessorContext.java?view=markup
{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 ?
