NIFI-4473 - fixed NPE in parametrized queries
----
> Add support for large result sets and normalizing Avro names to SelectHiveQL
> ----------------------------------------------------------------------------
>
> Key: NIFI-4473
> URL: https://issues.apache.org/jira/browse/NIFI-4473
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Fix For: 1.5.0
>
>
> A number of enhancements were made to processors like QueryDatabaseTable to
> allow for such things as:
> - Splitting result sets into multiple flow files (i.e. Max Rows Per Flowfile
> property)
> - Max number of splits/rows returned (Max fragments)
> - Normalizing names to be Avro-compatible
> The RDBMS processors also now support Avro logical types, but the version of
> Avro needed by the current version of Hive (1.2.1) is Avro 1.7.7, which does
> not support logical types.
> These enhancements were made to JdbcCommon, but not to HiveJdbcCommon (the
> Hive version of the JDBC utils class). Since Hive queries can return even
> larger result sets than traditional RDBMS, these properties/enhancements are
> at least as valuable to have for SelectHiveQL.
