where in livy is the hive configuration the equivalent of %jdbc - hive.url parameter. When I am running %livy.sql show tables, I get an empty result. I looked under livy interpreters section in zeppelin and also in ambari livy configs section but did not see an explicit hive url metastore location defined.
livy will use hive-site.xml under /etc/spark/conf. Make sure you have correct configuration in that file.
