Work Description: kasakrisz opened a new pull request, #3802:
URL: https://github.com/apache/hive/pull/3802
### What changes were proposed in this pull request?
Refactor the way ctas is executed:
* Do not create the table in `HiveIcebergSerDe` since it is also created at
compile time.
* Add a DDLTask before the `TezTask` to create the Iceberg table.
* Collect the properties added to jobconfig from the Serde object and
location and fileio from HiveCatalog. Location can be calculated at compile
time using `SemanticAnalyzer.getCtasOrCMVLocation`
* Persist the new table metaobject to a temp file when committing the table
creation.
* Read back the table metaobject anytime it is required from the TezTask and
the MoveTask.
### Why are the changes needed?
