[jira] [Commented] (PIG-2455) Need a way to get Pig's version programmatically.

    [ https://issues.apache.org/jira/browse/PIG-2455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13178338#comment-13178338 ] 

Harsh J commented on PIG-2455:
------------------------------

Apache Hadoop runs a script that saves version strings (from mvn/ant) into the package-info.java upon a build. So it should be fairly straightforward to maintain this as well, once you have a similar script added to Pig (i.e. You need only maintain versions in the same way as you do already, but have the script added to the execution when compiling, to take effect).

> There seems to be no API in Apache Pig that provides back a version string, or anything of that sort. For Apache Hadoop and HBase, we have VersionInfo classes doing this.
> I'm up for providing a patch if you guys feel this is worth maintaining (you'd need to maintain a package-info.java with some strings, as you change versions/revisions, I can look at how hadoop maintains this and help).
> I came across this thought while trying to think of an easy way around OOZIE-623.
