Subject [jira] [Commented] (HIVE-9456) Make Hive support unicode with MSSQL as Metastore backend

Thejas M Nair commented on HIVE-9456:
-------------------------------------

Agree, precommit tests won't help for this.

Note that this is kicking off  PreCommit-HIVE-METASTORE-Test (not the trunk test), however,
that does not work with MSSQL AFAIK.

> There are significant issues when Hive uses MSSQL as metastore backend to support unicode,
since MSSQL handles varchar and nvarchar datatypes differently. Hive 0.14 metastore mssql
script DDL was using varchar as datatype, which can't handle multi-bytes/unicode characters,
e.g., Chinese chars. This JIRA is going to track implementation of unicode support in that
case.
