Hi Dmitry
Yes. I can confirm that this is an issue. But the issue seems to be with vectorized execution and not with ORC. If I disable vectorization the query seems to work fine even for ORC tables. I will dig through the JIRAs to see if this is a known issue else I will file a bug. Thanks for reporting. - Prasanth On Thu, Oct 16, 2014 at 1:30 AM, Dmitry Tolpeko <[email protected]> wrote: > Hi, > With ORCFiles data inserted into the first table only.
