@dstreev - multiple lines support was added for PutHiveQL only, not
SelectHiveQL, right?
> HiveQL processor improvements (Multi-Statement Scripts in PutHiveQL, CSV

> Key: NIFI-3031
> URL: https://issues.apache.org/jira/browse/NIFI-3031
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.2.0
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Fix For: 1.2.0
>
>
> 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.
> Also, since SelectHiveQL offers CSV as an output format, an improvement would
> be to include properties (with existing defaults) for things like "Include
> Header in Output", "Alternate CSV Header", "CSV Delimiter", "Quote CSV" and
> "Escape CSV"
