[jira] [Created] (HIVE-3197) Hive compile errors under Java 7 (JDBC 4.1)

Brian Bloniarz created HIVE-3197:
------------------------------------

             Summary: Hive compile errors under Java 7 (JDBC 4.1)
                 Key: HIVE-3197
                 URL: https://issues.apache.org/jira/browse/HIVE-3197
             Project: Hive
          Issue Type: Bug
         Environment: Ubuntu 12.04
            Reporter: Brian Bloniarz


Hi, I've been trying to compile Hive trunk from source and getting failures:

{code}
    [javac] hive-svn/jdbc/src/java/org/apache/hadoop/hive/jdbc/HiveCallableStatement.java:48: error: HiveCallableStatement is not abstract and does not override abstract method <T>getObject(String,Class<T>) in CallableStatement
    [javac] public class HiveCallableStatement implements java.sql.CallableStatement {
    [javac]        ^
    [javac]   where T is a type-variable:
    [javac]     T extends Object declared in method <T>getObject(String,Class<T>)
{code}

I think this is because JDBC 4.1 is part of Java 7, and is not source-compatible with older JDBC versions. Any chance you guys could add JDBC 4.1 support?
