> HDFS-11156 was reverted because the implementation was non optimal, based on
> the suggestion from [~shahrs87], we should avoid creating a dfs client to get
> block locations because that create extra RPC call. Instead we should use
> {{NamenodeProtocols#getBlockLocations}} then covert {{LocatedBlocks}} to
> {{BlockLocation[]}}.
