> So I execute "explain select no from UnionPartionBool" to see the partition
> column, and find the partition column type is string.
> And all the partition column type is changed to be
> TypeInfoFactory.stringTypeInfo. It is in
> org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.genTablePlan(). And it is
> todo task. Now I modify it to be
> TypeInfoFactory.getPrimitiveTypeInfo(part_col.getType()).It can fix this bug.
> And you can see what I modified in the patch.
