             Summary: SCM throws NPE during JMX call
                 Key: HDDS-5421
                 URL: https://issues.apache.org/jira/browse/HDDS-5421
             Project: Apache Ozone
          Issue Type: Bug
          Components: SCM
            Reporter: Nanda kumar
            Assignee: Nanda kumar


Whenever there is a JMX call to SCM, there is an NPE in SCM log file.

JMX call invokes _StorageContainerManager#getScmRatisRoles_
{code:java}
  @Override
  public String getScmRatisRoles() throws IOException {
    return HddsUtils.format(getScmHAManager().getRatisServer().getRatisRoles());
  }
{code}
When in NON-HA mode the below call is returning null, causing NPE during JMX call.
{code:java}
SCMHAManager#getRatisServer(){code}
