----------------------------------------------
> ... Nicholas, is there some reason you prefer keeping this as a single method?
I don't have a strong preference except for compatibility. I agree with you
that the setSafeMode method is misleading.
I took a quick look at the patch. I think it is good enough for this issue.
Aaron, see if you want to review it. Or I can take another look at it in more
details.
> DFS#isInSafeMode needs to execute only on Active NameNode

> Currently DFS#isInSafeMode is not Checking for the NN state. It can be
> executed on any of the NNs.
> But HBase will use this API to check for the NN safemode before starting up
> its service.
> If first NN configured is in standby then DFS#isInSafeMode will check standby
> NNs safemode but hbase want state of Active NN.
