this JIRA can not be a blocker for HDFS-11150. SO, I suggest, fix #1 as part
of HDFS-11150 and proceed as that is more important task.

Agree, I will go back to HDFS-11150. Since #2 has been addressed, the last
issue seems belong to retry mechanism. I'm thinking about removing/changing
this JIRA.

> Recently I've found in some conditions, SPS is not stable:
> * SPS runs under safe mode.
> * There're some overlap nodes in the chosen target nodes.
> * The real replication number of block doesn't match the replication factor.
> For example, the real replication is 2 while the replication factor is 3.
