Subject [jira] [Created] (SQOOP-3397) Java version issues with Sqoop on AWS EMR

             Summary: Java version issues with Sqoop on AWS EMR
                 Key: SQOOP-3397
                 URL: https://issues.apache.org/jira/browse/SQOOP-3397
             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.4.7
         Environment: Amazon EMR emr-5.14.0 and up.
            Reporter: Devin G. Bost


The current build of Sqoop 1.4.7 appears to require Java 7. 

The version of Sqoop 1.4.7 on Amazon's Elastic Map Reduce (EMR) platform appears to be running
on Java 8. 

We need a way to be able to build Sqoop extensions on Java 8 so that they are compatible
with the version of Java running on the EMR versions of Sqoop. Otherwise, when attempts to
run the extension of Sqoop are made (such as for a custom Manager class), Java version mismatch
errors occur that block compilation of the class files that need to be generated for imports. 

How can we build Sqoop 1.4.7 on Java 8 so that extensions and plugins can be built with Java
8 so that they will still be compatible with the architecture of the other Apache tools (such
as Hadoop) that otherwise break on EMR instances when the Java version must be switched to
Java 7 to support Sqoop extensions and plugins?
