>          Components: Metastore
>    Affects Versions: 0.14.0

> hive-schema-0.15.0.mssql.sql has PARTITIONS.PART_NAME as NVARCHAR but COMPLETED_TXN_COMPONENTS.CTC_PARTITON,
COMPACTION_QUEUE.CQ_PARTITION, HIVE_LOCKS.HL_PARTITION, TXN_COMPONENTS.TC_PARTITION all use
VARCHAR.  This cannot be right since they all store the same value.
> the same is true of hive-schema-0.14.0.mssql.sql and the two corresponding hvie-txn-schema-...
files.
