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 , HBase  or Pig 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  preventing the compilation with JDK6
- We could use JDK7 specific language features in the source code
