Limess opened a new issue #3945:
URL: https://github.com/apache/hudi/issues/3945
**Describe the problem you faced**
We're running a deltastreamer job into a new Hudi table.
We have a partition column: `story_published_partition_date`, and we set
`hoodie.datasource.write.drop.partition.columns=true`.
When the execution completes, we observe that the partition column is
present in the parquet file, and data:
```shell
parquet-tools show
s3://<bucket>/articles_hudi_copy_on_write_drop_partition_column_test/story_published_partition_date=2021-01-07/b4eec094-ea1e-4b95-839f-648592eddb08-0_18-26-3681_20211108115747.parquet
--head 1 --columns story_published_partition_date --awsprofile signal-prod

The properties file referenced above contains:
```
hoodie.datasource.hive_sync.jdbcurl=jdbc:hive2://${EMR_MASTER_URL}:10000
hoodie.datasource.hive_sync.support_timestamp=true
hoodie.insert.shuffle.parallelism=${PARALLELISM}
hoodie.upsert.shuffle.parallelism=${PARALLELISM}
hoodie.bulkinsert.shuffle.parallelism=${PARALLELISM}
hoodie.write.markers.type=TIMELINE_SERVER_BASED
hoodie.datasource.hive_sync.support_timestamp=true
hoodie.metrics.on=true
hoodie.metrics.reporter.type=PROMETHEUS
hoodie.cleaner.commits.retained=1
hoodie.avro.schema.validate=true
```
**Expected behavior**
The column does not exist in the parquet file.
