Writing Data

Caused by: org.apache.parquet.io.InvalidRecordException: Parquet/Avro schema mismatch: Avro field 'col1' not found

This will usually happen when you are trying to add a new column to existing hive table using our HiveSyncTool.java class. Databases usually will not allow to modify a column datatype from a higher order to lower order or cases where the datatypes may clash with the data that is already stored/will be stored in the table. To fix the same, try setting the following property - 

set hive.metastore.disallow.incompatible.col.type.changes=false;
