Brad Ruderman created HIVE-4631:
-----------------------------------
Summary: Hive doesn't flush errors of multi-stage queries to
STDERR until end of query
Key: HIVE-4631
URL: https://issues.apache.org/jira/browse/HIVE-4631
Project: Hive
Issue Type: Bug
Components: CLI
Affects Versions: 0.9.0
Reporter: Brad Ruderman
Priority: Minor
When running a multi-stage query from the CLI for example
say the query is:
SELECT COUNT(*) FROM (
SELECT user from users
where datetime = 05-10-2013
UNION ALL
SELECT user from users
where datetime = 05-10-2013
) a
and the command to execute it:
hive -e "<query>"
If one of the jobs fails for example the 1st of 3, it should immediately write
that to the standard error and flush it. Therefore if you are scripting a hive
query you can catch the exception and terminate the other jobs rather then
having to wait for them to run to handle the exception from the first job.
