cbts-alec-johnson opened a new issue, #8857:
URL: https://github.com/apache/hudi/issues/8857
**Describe the problem you faced**
Column comments are not synced to the AWS Glue Data Catalog when setting
`hoodie.datasource.hive_sync.sync_comment` to `true` and adding column comments
in the dataframe schema metadata.
**To Reproduce**
Steps to reproduce the behavior:
1. Add a comment to a field in a dataframe.
2. Set `hoodie.datasource.hive_sync.sync_comment` to `true`
3. Write the dataframe to the AWS Glue Catalog
4.
```python
df = df.withMetadata('col1', {'comment': 'description of the column'})
```
**Expected behavior**
Setting `hoodie.datasource.hive_sync.sync_comment` to `true` when the
dataframe has column comments should sync the comments to the Glue Catalog.
**Environment Description**
* Hudi version : 0.12.1
* Spark version : 3.3.0
* Hive version :
* Hadoop version :
* Storage (HDFS/S3/GCS..) : S3
* Running on Docker? (yes/no) : no
**Additional context**
It looks like the comment is manually set to empty in this function here. It
should instead get the comment from the dataframe schema metadata.
