> This jira is a follow-on work of HDFS-8786, where we do decommissioning of
> datanodes having striped blocks.
> Now, after decommissioning it requires to change the ordering of the storage
> list so that the decommissioned datanodes should only be last node in list.
> For example, assume we have a block group with storage list:-
> d0, d1, d2, d3, d4, d5, d6, d7, d8, d9
> mapping to indices
> 0, 1, 2, 3, 4, 5, 6, 7, 8, 2
> Here the internal block b2 is duplicated, locating in d2 and d9. If d2 is a
> decommissioning node then should switch d2 and d9 in the storage list.
