## What changes were proposed in this pull request? Make client priority read from `IN_SERVICE` status Datanode. When Ozone client read Block form Datanode, the SCM will return all the Datanodes where the replicas are located, including the nodes in the `IN_MAINTENANCE`, etc state, and the order may be random, so if the client tries to access the `IN_MAINTENANCE` state node first. Sometimes, we set a Datanode to `IN_MAINTENANCE`, this may be due to some faults of the machine or wanting to restart a Datanode, in this scenario, that the Client does not read data form these `IN_MAINTENANCE` datanode is a good strategy. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-10593 ## How was this patch tested?
