Sushanth Sowmyan commented on HIVE-9456:
----------------------------------------

The precommit tests failed because it took the branch-1.2 attachment as the latest patch to
test:

{noformat}
+ grep -q 'ATTACHMENT ID: 12729763' /tmp/tmp.O03e6AgB80
+ shopt -s nocasematch
++ basename /jira/secure/attachment/12729763/HIVE-9456.branch-1.2.patch
+ PATCH_NAME=HIVE-9456.branch-1.2.patch
+ [[ HIVE-9456.branch-1.2.patch =~ ^HIVE-[0-9]+(\.[0-9]+)?(-[a-z0-9-]+)?\.(patch|patch.txt)$
]]
+ [[ HIVE-9456.branch-1.2.patch =~ ^(HIVE-[0-9]+\.)?D[0-9]+(\.[0-9]+)?\.(patch|patch.txt)$
]]
+ fail 'Patch HIVE-9456.branch-1.2.patch does not appear to be a patch'
+ echo 'Patch HIVE-9456.branch-1.2.patch does not appear to be a patch'
Patch HIVE-9456.branch-1.2.patch does not appear to be a patch
+ exit 1
+ rm -f /tmp/tmp.O03e6AgB80

> 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.
