Subject [jira] [Commented] (HIVE-4470) HS2 should disable local query execution
Date Fri, 26 Jul 2013 20:21:49 GMT


Gunther Hagleitner commented on HIVE-4470:

[~appodictic] Can you explain what you mean by that some more? You mean an admin can set defaults,
but we can't make sure someone submitting a query doesn't overwrite it? HiveConf only exists
on the server in this case, so does the rest of the planning/submission code. Why wouldn't
be be able to limit the user in what they can do?

> Hive can run queries in local mode (instead of using a cluster), if the size is small.
This happens when "" is set to true.
> This would affect the stability of the hive server2 node, if you have heavy query processing
happening on it. Bugs in udfs triggered by a bad record can potentially add very heavy load
making the server inaccessible. 
> By default, HS2 should set these parameters to disallow local execution or send and error
message if user tries to set these.
