Vadim Lositski created ZEPPELIN-1996:
----------------------------------------
Summary: Scheduled execution of JDBC alias interpeters (like
%hive) fails
Key: ZEPPELIN-1996
URL: https://issues.apache.org/jira/browse/ZEPPELIN-1996
Project: Zeppelin
Issue Type: Bug
Components: zeppelin-zengine
Affects Versions: 0.6.0
Environment: HDP 2.5.3, Zeppelin 0.6.0
Reporter: Vadim Lositski
We have configured following paragraph to run periodically (scheduled cron job
functionality)
{code}
%hive
select current_timestamp
{code}
This fails with following exception in the logs:
ERROR [2017-01-20 23:59:00,003] ({DefaultQuartzScheduler_Worker-9}
QuartzScheduler.java[schedulerError]:2425) - Job (note.2C8WZQ8HT threw an

I suspect that alias intepreters are not handled correctly when running from
scheduler, please fix this
