             Summary: Remove mixed partitions/table schema support
                 Key: HIVE-18113
                 URL: https://issues.apache.org/jira/browse/HIVE-18113
             Project: Hive
          Issue Type: Sub-task
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich


Currently it is possible to have misaligned table/partition schemas;

[see here for example| 
https://github.com/apache/hive/blob/a5c2e15c7cc125d8cda2ee3a8ed64c116ff6b755/ql/src/test/queries/clientpositive/schema_evol_text_vec_part.q#L156]

result of [this insert 
statement|https://github.com/apache/hive/blob/a5c2e15c7cc125d8cda2ee3a8ed64c116ff6b755/ql/src/test/queries/clientpositive/schema_evol_text_vec_part.q#L162]
 are these [null 
values|https://github.com/apache/hive/blob/a5c2e15c7cc125d8cda2ee3a8ed64c116ff6b755/ql/src/test/results/clientpositive/llap/schema_evol_text_vec_part.q.out#L660]

This mixed partition setup can cause the stats aggregation to become quite 
confusing...I think it would be better to remove this thing....there is a 
{{CASCADE}} flag already; which changes the schema all over the 
table/partitions/etc.
