Hi,
I'm trying to use the new concatenate command merge small ORC files and
file right away:
alter table requests partition(day_ts=1418083200, hour_ts=1418151600)
concatenate;
Diagnostic Messages for this Task:

Is there some property I need to set for ORC to be able to support
concatenation?
Thanks,
