Post upgrade we are having a TON of problems hive problems.

Most recently it's not taking over a minute just to select a hive database.

    $ hive
    WARNING: org.apache.hadoop.metrics.jvm.EventCounter is deprecated. Please use org.apache.hadoop.log.metrics.EventCounter in all the files.
    Logging initialized using configuration in jar:file:/opt/mapr/hive/hive-0.13/lib/hive-common-0.13.0-mapr-1501.jar!/
    hive> use hive_flow;
    Time taken: 63.499 seconds

Not sure where to even begin.  I assume it's a metastore problem.

We are also getting errors when trying to query some tables...all happened post upgrade...not sure if it's all related.

I believe we essentially upgraded from hive 0.11 to 0.13 during the upgrade process.
