-----------------------------------------

             Summary: Drop JDK6 support
                 Key: SQOOP-2454

             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.99.6, 1.4.6
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho

[Following our mailing list discussion|http://markmail.org/thread/6jodptl3to2lsfsi]:

JDK6 has been officially put end of life by Oracle more then 2 years ago
(February 2013). Other projects in Hadoop ecosystems have already dropped JDK6 support - for example Hadoop [1], HBase [2] or Pig[3] and hence I would like to kick off discussion to do the same in Sqoop as well.

What exactly that would mean for our users:
* User would need to use at least JDK7 on the runtime - we’re spawning mapreduce job, so entire cluster would have to be running on at least JDK7

What would that mean for Sqoop developers:
* We would change our build scripts to use -source and -target 1.7 [4] preventing the compilation with JDK6
* We could use JDK7 specific language features in the source code [5]
