> In HDFS-1314 and HDFS-9842, it had make some configurations can be friendly accept multiply
size unit, such as 134217728 can be also 128m, or 8048, can be also replaced by 8k. And in
some configurations, the value will be large, like in {{dfs.datanode.available-space-volume-choosing-policy.balanced-space-threshold}},
its default value is 10g, equal to 10737418240. Obviously, it's not convenient to direct transform.
So we could make some hdfs bytes-default configurations which without size unit name  be friendly
accepted multiply size unit.
