d125q opened a new issue, #9542:
URL: https://github.com/apache/iceberg/issues/9542
### Apache Iceberg version
1.4.3 (latest release)
### Query engine
Spark
### Please describe the bug 🐞
Assume `glue_catalog` is configured to use GlueCatalog. Now, execute
something along the lines of:
```python
df = spark.createDataFrame(
[
("foo", 23),
("bar", 41),
("baz", 27),
],
"name: string, age: int"
)
df = df.select(
F.col("name").alias("name", metadata={"comment": "Name column comment"}),
F.col("age").alias("age", metadata={"comment": "Age column comment"})
)
(
df
.writeTo("glue_catalog.glue_database.glue_table")
.tableProperty("comment", "Table comment")
.createOrReplace()
)
```
The column comments are indeed added to the Glue table, but the table
comment itself is not. (Glue calls it a table _description_, but anyway.)
Looking at
[IcebergToGlueConverter](https://github.com/apache/iceberg/blob/e32df0ce08086758c44e9174c582638068244073/aws/src/main/java/org/apache/iceberg/aws/glue/IcebergToGlueConverter.java#L53),
I see the [code responsible for adding the column
comments](https://github.com/apache/iceberg/blob/e32df0ce08086758c44e9174c582638068244073/aws/src/main/java/org/apache/iceberg/aws/glue/IcebergToGlueConverter.java#L320),
but I see nothing of the like for table comments.
