Work Description: InvisibleProgrammer commented on PR #4252:
URL: https://github.com/apache/hive/pull/4252#issuecomment-1522384762
I started to play with the porting, let me share some extra information and
details:
There are two modules that we 'copy' into Hive: `mr` and `hive-metastore`.
When we do a Hive-Iceberg upgrade, it is worth checking if is there anything
that should be ported from there as well - or otherwise, we can get unexpected
behavior.
I was able to narrow down the promising commits to 7:
To gather them, I got the git commits between the 1.1.0 and 1.2.1 tags but
only for the mr and hive-metastore folders with those commands:
```
zsoltmiskolczi@zsmiskolczi-MBP16 iceberg % git log
apache-iceberg-1.1.0...apache-iceberg-1.2.1 --pretty=tformat:"%H %s %cs"
--reverse
