    [CARBONDATA-581] Wrong number of executors requested when preferred locations are not

    Wrong number of executors requested when preferred locations are not obtained.
    In case of groupby in subquery, we'll not get the preferred locations from the RDD as
data is shuffled.
    In such cases we need to use number of executors available.
    This is applicable in case of dynamic executors
