Gabor Kaszab commented on IMPALA-8600:
--------------------------------------
I ran into a Hive issue during the implementation: Hive doesn't increment any
writeIds if I change the schema of a partitioned ACID table. It increments the
high watermark, however. I opened a Jira:

> Reload partition does not work for transactional tables

> If a table is transactional, a reload partition call should fetch the valid
> writeIds. Without doing this, the reload will skip adding all the newly
> created delta files of the transactional table pertaining to the new writeIds.
