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.
> Make Hive support unicode with MSSQL as Metastore backend

> 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.
