> 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.
