Hi Hoss, In RegexReplaceProcessorFactory, this line means that you can't use match groups in the replacement string:
replacement = Matcher.quoteReplacement(replacementParam.toString()); What's the reasoning behind this? Or am I missing something here, and groups can be used? It's making it hard for me to write up a simple solution to a training exercise, where students need to clean up incorrectly formatted dates :) Thanks, -- Ken -------------------------- Ken Krugler +1 530-210-6378 http://www.scaleunlimited.com custom big data solutions & training Hadoop, Cascading, Cassandra & Solr
