Matt Burgess commented on NIFI-5079:
------------------------------------
We considered this, but we don't know the implications of evicting the version
of Avro that Hive 1.2.1 wants (1.7.7) for a newer one (1.8.x). It seems to fix
this issue fine and supports logical types, but it may mess something else up
in the Hive client, so we thought it too dangerous. We can certainly re-open
the discussion here and/or on the mailing list if you like.
Another reason was that Hive 1.2.1 is quite out of date, hopefully folks will
get to Hive 3 sooner than later, and the logical types are all supported in the
Hive 3 versions of the processors and controller services.
> Add support for logical types to Hive DDL creation in PutORC

> While other processors have been updated to support Avro logical types (such
> as decimal, timestamp, etc.), ConvertAvroToORC does not currently support
> them. We should update ConvertAvroToORC to handle Avro logical types, not
> just in the conversion to ORC but also in the generated Hive DDL.
