    Description

      JDK7 build fails with following error

      [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hive-exec: Compilation failure
      [ERROR] /home/prasadm/repos/apache/hive-trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/persistence/LazyFlatRowContainer.java:[118,15] name clash: add(java.util.List<java.lang.Object>) in org.apache.hadoop.hive.ql.exec.persistence.LazyFlatRowContainer overrides a method whose erasure is the same as another method, yet neither overrides the other

      This LazyFlatRowContainer.java is a new file added as part of HIVE-6418 patch. It's extending AbstractCollection and implements AbstractRowContainer. Looks like the both these have a add() method that's conflicting.
