0.12.1 Zebra massive javadoc errors

[Konstantin Boudnik]

Guys,

Perhaps it isn't a news, but just wanted to put it out for the record. It
seems that javadoc for Zebra contrib is pretty much broken. There's a lot of
errors like

  [javadoc] 
/biggy/workspaces/bigtop/build/pig/deb/pig-0.12.1/contrib/zebra/src/java/org/apache/hadoop/zebra/mapreduce/BasicTableOutputFormat.java:400:
 error: cannot find symbol
  [javadoc]     public static Object getSortKeyGenerator(JobContext jobContext) 
throws IOException, ParseException {
  [javadoc]                                                                     
                    ^
  [javadoc]   symbol:   class ParseException
  [javadoc]   location: class BasicTableOutputFormat

and other kinds along with 300+ warnings.
