    Description

      The ShuffleHandler permanently remembers the list of "good" disks on NM startup. If disks later are added to the node then map tasks will start using them but the ShuffleHandler will not be aware of them. The end result is that the data cannot be shuffled from the node leading to fetch failures and re-runs of the map tasks.
