Re: FileNotFoundException when writting Hive orc tables

Hi Paul,

If your orc table has no complex(list,map,row) types, you can try to set `table.exec.hive.fallback-mapred-writer` to false in TableConfig. And Hive sink will use ORC native writer, it is a work-around way.

About this error, I think this is a bug for Hive 1.1 ORC. I will try to re-produce it.

I created https://issues.apache.org/jira/browse/FLINK-18659 to track this. If it is a bug, it should be fixed in 1.11.2

Best,

Jingsong

Hey Paul,

Could you please share more about your job, e.g. the schema of your Hive table, whether it's partitioned, and the table properties you've set?

Hi,

I'm doing a POC on Hive connectors and find that when writing orc format Hive tables, the job failed with FileNotFoundException right after ingesting data (full stacktrace at the bottom of the mail).

The error can be steadily reproduced in my environment, which is Hadoop 2.6.5(CDH-5.6.0), Hive 1.1.0(CDH-5.6.0) and Flink 1.11.0. It only happens in orc tables, while other bulk formats are fine.

Does anyone have an idea about this error? Any comment and suggestions are appreciated. Thanks!
