Hi Vijay,
The error you are receiving is generally caused by a mismatch in the data type between the parquet file and the hive metastore schema. One example of where this can occur is with a timestamp column, where the timestamp format between parquet and hive are different. I would check any date or timestamp columns and modify your Athena query to use a CAST function to convert it. Take a look at Data Types in Athena for more information.
Are you able to share the query or schema, which would have been asked in the rest of the error message you received? Then we can provide help with a specific CAST or other function based on the column that is having trouble converting intrinsically.
Thank you.
