             Summary: Avro/Parquet schemas can't handle Sqoop-generated non-alphanumeric column names
                 Key: SQOOP-1780
                 URL: https://issues.apache.org/jira/browse/SQOOP-1780
             Project: Sqoop
          Issue Type: Bug
    Affects Versions: 1.4.5
            Reporter: Josh Wills


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:

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
