Subject [jira] [Commented] (HIVE-9456) Make Hive support unicode with MSSQL as Metastore backend
Date Mon, 02 Feb 2015 23:22:34 GMT


Sushanth Sowmyan commented on HIVE-9456:

+1 to content, that looks reasonable to me.

There is one other thing to take care of though, before committing this. [~vikram.dixit]/[~brocknoland]/[~alangates]
: given that it's not 0.15 anymore but 1.2, what's the plan for db upgrade scripts? Should
we have a 0.14->1.0 without this, a 1.0->1.1 without this, and 1.1->1.2 with this?

> 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
