> In case there are multiple SBNs, and {{dfs.ha.allow.stale.reads}} is set to true, failover
could go to a SBN which then may serve read requests from client. This may not be the expected
behavior. This issue arises when we are working on HDFS-12943 and HDFS-12976.
> A better approach for this could be to check {{HAServiceState}} and find out the active
NN when performing failover. This also can reduce the # of failovers the client has to do
in case of multiple SBNs.
