   ### Change Logs
   
   Currently PartitionAwareClusteringPlanStrategy will list all partition in 
table whether PARTITION_SELECTED is set or not. List all partition in the 
dataset is a very expensive operation when the number of partition is huge. We 
can skip list all partition when PARTITION_SELECTED is set, so that clustering 
scheduling can benefit a lot from  partition pruning.
