codope opened a new pull request, #12014:
URL: https://github.com/apache/hudi/pull/12014
### Change Logs
If hive style partitioning is enabled, then url encoding is also enabled. We
need to do so otherwise the partition structure is awkward in some cases. For
example, a `partition` field with values like "dd/mm/yy" will be written as
three-level directory where the first level is `partition=dd` and then its
child is `mm`, and then `yy`.
```
partition=dd
|- mm
|- yy
```
With URL encoding enabled, it will be `partition=dd%2Fmm%2Fyy`.
### Impact
Correct partition strucutre. However, for a small subset of users who had
partitions in above format and hiev style paritioning enabled, this is going to
be a physical layout change.
### Risk level (write none, low medium or high below)
