For the said error ID, are there more messages in the log, which could give out more information?
Could you also share the query & profile (full JSON) for the query? May be you put it up on gist and share a link. Someone here could take a look. Try and increase the value for DRILL_MAX_DIRECT_MEMORY and see if that helps. Refer to https://drill.apache.org/docs/configuring-drill-memory/ for instructions. Also, to improve query performance, please see https://drill.apache.org/docs/performance-tuning-introduction/ On Wed, Sep 23, 2015 at 9:10 AM, Boris Chmiel < boris.chm...@yahoo.com.invalid> wrote: > Hi Abhishek, > It is probably due to OOM.
