> PROBLEM:
> Hive stats are autogathered properly till an 'analyze table [tablename] compute statistics
for columns' is run. Then it does not auto-update the stats till the command is run again.
repo:

> set hive.stats.fetch.column.stats=true; 
> set hive.stats.fetch.partition.stats=true ; 
> set hive.stats.reliable=false ; 
> set hive.compute.query.using.stats=true;
