ShreyeshArangath opened a new issue, #2029:
URL: https://github.com/apache/datafusion-comet/issues/2029
### Describe the bug
Built the most recent version of Comet for some internal benchmarking, but
running into this following issue
```
org.apache.spark.SparkException: Parquet column cannot be converted in file
hdfs://cluster/jobs/x/y/tpcds-unpartitioned/tpcds-1000/store_returns/part-00088-85e008a2-66d5-4ca4-a957-da1b024bc0ae-c000.snappy.parquet.
Column: [sr_return_amt], Expected: decimal(7,2), Found: DOUBLE.
```
I also tried to set
spark.conf.set("spark.sql.parquet.enableVectorizedReader","false") but that
didn't fix the issue (and I do not think that it is the recommended path). Any
help would be great! 🙂
