--------------------------------------------------------------
I found when the data is ec, and the number of replication is one, the
replication in ozone is also one
I think hdfs is ec data, hdfs distcp to the ozone, if the ozone is also stored
in ec, the copy will be based on the incoming value, if the ozone is not stored
in ec, is it reasonable to use 1 as the copy?
