[jira] [Created] (SQOOP-1283) Export doesn't detect Avro files
without .avro extension (ie created by Hive)
Hari Sekhon created SQOOP-1283:
----------------------------------
Summary: Export doesn't detect Avro files without .avro extension (ie created by Hive)
Key: SQOOP-1283
URL: https://issues.apache.org/jira/browse/SQOOP-1283
Project: Sqoop
Issue Type: Bug
Components: connectors/postgresql
Affects Versions: 1.4.3
Environment: CDH 4.5
Reporter: Hari Sekhon
Exporting to PostgreSQL, Sqoop doesn't detect Avro files properly if they don't have the .avro extension (ie they are called 000000_0 in HDFS as they were created by Hive) and falls back to unknown file type in the code, which then attempts to use Text export mapper which fails with a parse exception:
