FileNotFoundException when writting Hive orc tables
Locked
 
|
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!

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? On Tue, Jul 21, 2020 at 4:02 PM Paul Lam <[hidden email]> wrote:

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 On Tue, Jul 21, 2020 at 4:25 PM Rui Li <[hidden email]> wrote:

Hi Rui,
I reproduced the error with a minimum case, the SQL is similar to `insert into hive_table_x select simple_string from kafka_table_b`. I’m pretty sure it’s not related to the table schema. And I removed all the optional properties in the Hive table DDL, the error still happened. Best, Paul Lam

Hi JingSong,
Thanks for your advice! But IIUC, it seems that `table.exec.hive.fallback-mapred-reader` is false by default? Moreover, explicitly setting this option might cause a serialization issue. Wonder if I’m setting it in the right way? ``` tableEnv.getConfig().getConfiguration().setString("table.exec.hive.fallback-mapred-writer", "false”); ``` The error it caused: Caused by:

Hi Paul, I believe Jingsong meant try using native writer, for which the option key is `table.exec.hive.fallback-mapred-writer` and is by default set to true. You can set it to false like this: tableEnv.getConfig().getConfiguration().set( HiveOptions.TABLE_EXEC_HIVE_FALLBACK_MAPRED_WRITER, false) On Tue, Jul 21, 2020 at 6:07 PM Paul Lam <[hidden email]> wrote:

Hi, Sorry for this. This work around only works in Hive 2+. We can only wait for 1.11.2. Best, Jingsong On Tue, Jul 21, 2020 at 6:15 PM Rui Li <[hidden email]> wrote:

Thanks for your help anyway, Jingsong & Rui. I read the jira description, and I’m +1 to check the lazy initiation first. It looks like the file creation is skipped or it doesn’t block the writing, and I’ve seen a bucket was writing to a file that was not supposed to exist, e.g. its parent dir was not created yet.
