[jira] [Commented] (SQOOP-352) Export of avro data imported from
database table (using sqoop import) fails on year

Review request for Sqoop, Arvind Prabhakar, Tom White, and Jarek Cecho.
Summary
-------
MySQL YEAR is mapped to java.sql.Date when importing to HDFS. On the way back an exception is thrown because the date and month fields are truncated (not used) - this is the MySQL behaviour.
This addresses bug SQOOP-352.

> Report from Wing Yew Poon:
> I use a MySQL database for testing sqoop. I created a table with a representative collection of data types for the columns, excluding blob and text (and their different-sized variants).
> I run sqoop import --as-avrodatafile to import the table into hdfs.
> I create a second table with the same schema, and run sqoop export to export the avro data to this second table. The export fails with
