Description

We enabled the heterogeneous storage in our cluster and there are only ~50% of datanode & regionserver hosts with SSD. We set hfile with ONE_SSD storagepolicy but we found block's all replica are DISK often even local host with SSD storage. The block placement do not choose SSD first to place replica.
