      Description

      In its current form, the parallelCollectionScan command will only return multiple cursors when running a mongod with the MMAPv1 storage engine. With the deprecation of MMAPv1 we should also deprecate parallelCollectionScan.

      If the ability to partition a collection is required under WiredTiger in the future, it is likely it will take a different form than parallelCollectionScan. Once such request is tracked by SERVER-24274
