> We always pick the active HBase Master as quick links target url. So if there
> is no active Master (eg. all Masters stopped or Stand By), then the message
> "hostname is undefined" show up.
> The fix:
> To disable the HBase quick links if no active masters existed. (see attached
> fix.png.)
> Btw, when HDFS HA enabled, we also got situation where there is no Active NN,
> at that point we disabled these links. It is the same fix for this Jira.
