             Summary: Avoid unnecessary DatanodeDetails creation for NodeStateManager lookup
                 Key: HDDS-8854
                 URL: https://issues.apache.org/jira/browse/HDDS-8854
             Project: Apache Ozone
          Issue Type: Improvement
          Components: SCM
            Reporter: Attila Doroszlai
            Assignee: Attila Doroszlai


{code:title=https://github.com/apache/ozone/blob/0b6a16abbb61049406c3a8b1cdbb5fe06c74bceb/hadoop-hdds/server-scm/src/main/java/org/apache/hadoop/hdds/scm/node/NodeStateManager.java#L375-L377}
  public DatanodeInfo getNode(DatanodeDetails datanodeDetails)
      throws NodeNotFoundException {
    return nodeStateMap.getNodeInfo(datanodeDetails.getUuid());
{code}

Several callers create {{DatanodeDetails}} just for the lookup.  These could be avoided by an overloaded method accepting {{UUID}} directly.

Same for {{getNodeStatus}}.
