> 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[]}}.
