Subject Re: Disable Hive autogather optimization
Date Wed, 27 Apr 2016 02:32:45 GMT
Update: Realized this works if we create a fresh table with this config
already disabled but does not work if there is already a table created when
this config was enabled. We now need to figure out how to disable this
config for a table created when this config was true.
