> I was importing a MySQL table that had columns that started with a number (1QP, 2QP, etc.). It looks like Sqoop appends an underscore on the front of those names to make them compatible with Hive, but Parquet/Avro schemas can't handle the non-alphanumeric value in the name of a field (or at least, at the start of it), throwing the following exception:
> {code}
> java.lang.IllegalStateException: Deprecated: field names are not alphanumeric (plus '_'): sqoop_import_team._1QP, sqoop_import_team._2QP, sqoop_import_team._3QP, sqoop_import_team._4QP
