    Description

      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.
