Description

Currently, `DROP TABLE IF EXISTS` shows warning for non-existing tables. However, it had better be quiet for this case by definition of the command.

scala> sql("DROP TABLE IF EXISTS nonexist")
16/11/20 20:48:26 WARN DropTableCommand: org.apache.spark.sql.catalyst.analysis.NoSuchTableException: Table or view 'nonexist' not found in database 'default';
