---------------------------------------
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.
