Koji Kawamura commented on NIFI-2624:
-------------------------------------

Although this JIRA included SelectHiveQL in its scope originally, we have 
implemented Avro logical type support only at ExecuteSQL and 
QueryDatabaseTable. SelectHiveQL does NOT support logical as of this writing.

NIFI-3093 tries to add Hive support for ExecuteSQL and QueryDatabaseTable. Once 
it's done, Hive tables can be queried with Avro logical types with ExecuteSQL 
or QueryDatabaseTable.

> The original SQL processors implemented BigDecimal values as Strings for 
> Avro, as the version of Avro it used (1.7.6) did not support DECIMAL type.
> As of Avro 1.7.7 (AVRO-1402), this type is supported and so the SQL/HiveQL 
> processors should be updated to handle BigDecimals correctly if possible.
