xubo245 updated CARBONDATA-2088:
--------------------------------
    Description:
change using 'timeseries' instead of using preaggregate for creating timeseries pre-aggregate table

change timeseries.eventTime and hour_granularity and so on
granularity only support one

It should throw UnsupportDataMapException if don't use timeseries or preaggregate to create datamap

  was:
It better using ‘timeseries_cube’ instead of ‘preaggregate’ for timeseries pre-aggregate table ,because:

{code:java}
1. It is a cube that understands the dimension hierarchy of time, it is not a simple preaggregate table
2. This datamap creates multiple pre-aggregate tables, not just one. And DROP DATAMAP command will drop multiple table too.

{code}

and change

{code:java}
timeseries.eventTime  =>eventTime
timeseries.hierarchy　＝＞hierarchy
{code}
