Subject [jira] [Commented] (HIVE-8550) Hive cannot load data into partitioned table with Unicode key
Date Tue, 21 Oct 2014 23:55:34 GMT


Xiaobing Zhou commented on HIVE-8550:

If MSSQL is metastore and unicode chars support is expected, for a fresh installation or legacy
system that doesn't involve multi-bytes support, varchar-to-nvarchar upgrade works fine, however,
the upgrade seems impossible for on-going Hive system, because MSSQL doesn't allow schema
change on varchar typed primary key or index, which is typical Hive use case.

Any thoughts on how to do this upgrade? Thanks!
