Subject Re: Branch for HIVE-10511: Replacing the implementation of Hive CLI using Beeline
Date Fri, 01 May 2015 21:24:44 GMT
What sort of issue do you see ? Is it some memory leak ?
Most of the issues I saw getting filed recently happens when HS2 uses
remote metastore.
Can you try switching to use embedded metastore (hiveserver2
--hiveconf hive.metastore.uris=' '). For multiple reasons (including
historic reason of their being a bug with use of remote metastore in
old version of HS2), the hortonworks default configuration has been
using embedded metastore.
