Hi Sergio, Thanks for your reply.
I found one such effort : https://issues.apache.org/jira/browse/HIVE-6784 I consider to try it differently. Similar stuffs in ORC: https://issues.apache.org/jira/browse/HIVE-10591 Regards, Mohammad On Wednesday, October 7, 2015 8:58 AM, Sergio Pena <sergio.p...@cloudera.com> wrote: Hi Mohammad, Currently, Hive + Parquet does not support auto casting for wider types. That is be a very good idea to implement in Hive. I'll investigate the hive + parquet code, and see if it is something we can add in a future release. - Sergio On Tue, Oct 6, 2015 at 7:23 PM, Mohammad Islam <misla...@yahoo.com.invalid> wrote: > > Any hive+parquet user/dev to address this? > > > Regards, > Mohammad > > On Monday, October 5, 2015 3:41 PM, Mohammad Islam <misla...@yahoo.com> > wrote: > > > > Hi, > Does the parquet table support auto casting to wider data types?
