Testing (updated)
-------
This is how the priority section looks:
```
Priority Ranges. The numbers are the costs of the query.
The cost is calculated based on partition weights and fact weights. The
interpretation of the default config is:
cost <= 7 : Priority = VERY_HIGH
7 < cost <= 30 : Priority = HIGH
30 < cost <= 90 : Priority = NORMAL
90 < cost : Priority = LOW
Some perspective wrt default weights and default ranges(1 for hourly, 0.75 for
daily, 0.5 for monthly):
For exclusively hourly data this translates to
VERY_HIGH,7days,HIGH,30days,NORMAL,90days,LOW.
FOR exclusively daily data this translates to
VERY_HIGH,9days,HIGH,40days,NORMAL,120days,LOW.
for exclusively monthly data this translates to
VERY_HIGH,never,HIGH,1month,NORMAL,6months,LOW.
One use case in range tuning can be that you never want queries to run with
VERY_HIGH, assuming no other changes, you'll modify the value of this param in
hivedriver-site.xml to be HIGH,30.0,NORMAL,90,LOW
via the configs, you can tune both the ranges and partition weights. this would
give the end user more control.
```
