Description

Currently during registration of a data-node with the storage id that has already been registered
the name-node logs 2 records: <add node1> <remove node2>.
If the same node has been restarted these two records are redundant, lead to unnecessary
increase of the edits file and result in a slow-down of the name-node startup.
