Status: Resolved (was: Patch Available)
> PutHive3Streaming does not correctly support all Hive types
> -----------------------------------------------------------
>
> Key: NIFI-5517
> URL: https://issues.apache.org/jira/browse/NIFI-5517
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
> Fix For: 1.8.0
>
>
> NIFI-5475 upgraded the version of Hive 3 to Apache Hive 3.1.0, and some code
> changes had to be made as there were new Writable types to be used in place
> of the old ones. As a result of the upgrade, NIFI-5491 was discovered and
> included some fixes for PutHive3Streaming to support various primitive data
> types as well as structs.
> However it appears that NIFI-5491 did not cover all the available Hive types,
> and NIFI-5475's changes were to PutORC for time/date types, but similar
> changes have been made to the Hive writer as well.
> PutHive3Streaming should support all available Hive types where prudent (i.e.
> where NiFi Record Field Types can be converted to Hive Column Types). The
> current list of "top-level" types include:
> PRIMITIVE, LIST, MAP, STRUCT, UNION
> And the current list of PRIMITIVE types include:
> VOID, BOOLEAN, BYTE, SHORT, INT, LONG, FLOAT, DOUBLE, STRING,
> DATE, TIMESTAMP, TIMESTAMPLOCALTZ, BINARY, DECIMAL, VARCHAR, CHAR,
> INTERVAL_YEAR_MONTH, INTERVAL_DAY_TIME, UNKNOWN
> As of NIFI-5475 I believe PutHive3Streaming supports BOOLEAN, BYTE, SHORT,
> INT, LONG, FLOAT, DOUBLE, STRING, VARCHAR, and CHAR for primitive types, and
> with respect to the supported primitive types, PutHive3Streaming supports
> LIST, MAP, STRUCT, and UNION.
> The remaining list of primitive types is DATE, TIMESTAMP, BINARY, and
> DECIMAL. VOID and UNKNOWN are used "under the hood" I believe, and ORC
> doesn't currently support TIMESTAMPLOCALTZ. INTERVAL_YEAR_MONTH and
> INTERVAL_DAY_TIME are only valid for queries and not as column types.
