Sergey Shelukhin commented on HIVE-19916:
-----------------------------------------
Attached the master patch (whole branch + this patch) for HiveQA. If we see
actual failures in optimizer, then those would need to be fixed (because
getting writeIds twice with the current double compile scheme where optimizers
run outside of lock could mean incorrect results). If some DDL paths fail then
we'd postpone... if none fail (compared to the branch itself) we'd commit.
> master-txnstats branch - don't get write IDs from metastore when it's not safe

> There's some code in original txn stats patch that may go to metastore to get
> write Ids. This code should not go to metastore, it should fail instead.
> HIVE-19382 should ensure that we have correct IDs already present during
> optimizer - they are using by e.g. materialized view optimizer, so they
> should be there; if they are not present, some integration might be needed so
> that txn stats optimizations also have access to those write Ids.
