Josh Wills created SQOOP-1780:
---------------------------------
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
