------------------------------------
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?
