Sumit Agrawal commented on HDDS-9660:
-------------------------------------
836 @VisibleForTesting
837 public RaftPeerId getRaftLeaderId() {
838 return this.getLeader() == null ? null : this.getLeader().getId();
839 }
There is a very rare chance that first call "getLeader()" is not null, but
second call getLeader() is null as depends on state of raft at the particular
time.
So need get value to local variable and use that to return Id.
