> Trying to use the PutHiveQL processor to execute a HiveQL script that contains multiple statements.
> IE: 
> USE my_database;
> FROM my_database_src.base_table
> INSERT OVERWRITE refined_table
> SELECT *;
> -- or --
> use my_database;
> create temporary table WORKING as
> select a,b,c from RAW;
> FROM RAW
> INSERT OVERWRITE refined_table
> SELECT *;
> The current implementation doesn't even like it when you have a semicolon at the end of the single statement.
> Either use a default delimiter like a semi-colon to mark the boundaries of a statement within the file or allow them to define there own.
> This enables the building of pipelines that are testable by not embedding HiveQL into a product; rather sourcing them from files.  And the scripts can be complex.  Each statement should run in a linear manner and be part of the same JDBC session to ensure things like "temporary" tables will work.
