Description
Document how REPLACE uses a Java regex and link out to JDK docs describing reserved characters and escaping. From recent confusion on the users list:
> String source = "[02/Aug/2012:05:01:17"; > > String target ="["; > > String replaceWith = ""; > > return source.replaceAll(source, target, replaceWith); > Note that Java String.replaceAll() takes a regular expression for the 2nd > parameter (i.e. target), and "[" is a special character. To use it as is, > you have to escape it, so in your Pig script, you should do: > REPLACE(date,'\\[','')
