> Oozie submits Pig jobs according to given Pig version. For example, Pig versions before 0.8 are treated in the following way:
>  [Main.main(args)|https://github.com/apache/oozie/blob/678f1b2b2cc9a2456c7e3d9f693d2637f1f03257/sharelib/pig/src/main/java/org/apache/oozie/action/hadoop/PigMain.java#L382]
> However, we dropped support for *Hadoop 1*, *Hadoop 0.23* support via {{OOZIE-2316}}. I wonder whether submitting jobs using Pig version before 0.8 will work at all:
> - https://pig.apache.org/releases.html#13+May%2C+2010%3A+release+0.7.0+available says "This release works with Hadoop 0.20". .
> - Looking at [PIG-2125|https://issues.apache.org/jira/browse/PIG-2125], I believe the answer is NO. 
> Therefore we can safely delete corresponding parts from the codebase. There is also another class {{PigMainWithOldAPI}} that is only used by tests in {{TestPigMainWithOldAPI}}. So we can remove these too.
