FAQ
Hello,
I found antomaton.jar file in lib directory. But I did not find automaton version in Pig-0.8.1.
My question are:
1. what is the automaton version of Pig-0.8.1?
2. Why automaton jar file is located in lib directory? What this jar file will be used for?
3. Could I replace lib/automaton.jar with automaton-1.7.2?
Thank you.

    I could not find the version number from the jar file either. But it
    would have the stable version for java 6 as of 11 Dec 2009. It was added
    as part of https://issues.apache.org/jira/browse/PIG-965

    See above link, it is used for matches clause.
    3. Could I replace lib/automaton.jar with automaton-1.7.2?
    I am not sure. Looking at the change logs, it seems like there have
    been multiple changes, including classes being rearranged. You can give
    it a try .
