[jira] [Closed] (DRILL-1350) Make sure default option values are handled correctly during upgrade

     [ https://issues.apache.org/jira/browse/DRILL-1350?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Krystal closed DRILL-1350.
--------------------------

Updated the value of some options using "alter systems ...".  Noted the default value for "planner.broadcast_threshold"=1000000.

Upgraded drill from 0.7 to 0.9.  Verified that the value for the updated options still remained the same.  Verified that the value for "planner.broadcast_threshold" now is 10000000

> When Drill is installed,  the various system options and their default values are  stored in zookeeper.  When upgrading to a new version, if these default options have changed in the new version, they are not reflected in Zookeeper and we continue to use the old default values.  This is an upgrade issue and should be handled correctly.
