> I have Hive, MySQL and Spark. MySQL is Hive metastore_db. I follow this guide to configurate it (http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/4.2.0/CDH4-Installation-Guide/cdh4ig_topic_18_4.html). It is ok for me to do drop table command under hive shell environment. But when I enter into spark-shell env, I use hiveContext.hql("DROP TABLE IF EXISTS hivetesting"). And then, I get following error:
> ERROR Hive: NoSuchObjectException(message:default.hivetesting table not found)

> I think when running under hive shell, it mutes this error. But under spark shell, hive doesn't mute this error and throw out error directly. So If the table doesn't exist, hive should not throw out error; it should throw out warning.
