Description

In different places, we use the following reflection-based code to reset a variable inside HiveConf.java

    public static void resetHiveConfStaticVariables() throws Exception {
        // HiveConf initializes location of hive-site.xml in static block.
        // So this is needed so that tests like TestHiveMain that create hive-site.xml don't fail.
        Field declaredField = HiveConf.class.getDeclaredField("hiveSiteURL");
        declaredField.setAccessible(true);
        declaredField.set(null, HiveConf.class.getClassLoader().getResource("hive-site.xml"));
    }

Note that HiveConf has supported setting hiveSiteURL for a long time. Even version 0.13.0 has the static setter method:

https://github.com/apache/hive/blob/branch-0.13/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java#L1493-L1495

Therefore reflection-based solution should be modified.
