Hive查询CLI工作正常，通过色相失败

Question

I have a weird issue with hue (version 3.10).

I have a very simple hive query:

drop table if exists csv_dump;
create table csv_dump row format delimited fields terminated by ',' lines terminated by '\n' location '/user/oozie/export' as select * from sample;

• running this query in the hive editor works
• running this query as an oozie workflow command line works
• running this query command line with beeline works
• running this query via an oozie workflow from hive fails

Fail in that case means:

• drop and create are not run, or at least do not have any effect
• a prepare action in the workflow will be executed
• the hive2 step in the workflow still says succeeded
• a following step will be executed.

Now I did try with different users (oozie and ambari, adapting the location as relevant), with exactly the same success/failure cases.

I cannot find any relevant logs, except maybe from hue:

Oozie Launcher ends

Where I see that beeline is started, but I do not see any mapper allocated as I do command line.

Would anybody have any idea of what could go wrong?

Thanks, Guillaume

As explained by @romain in the comments, new lines need to be added in the sql script. Then all is good.
