Hi!
In my case absolutely the same issue was fixed by disabling ipv6 on the
machine where cluster was started.

It was due to a missing lib jar which rendered region servers useless.
That's why I suggested checking out region server logs.

Nathan:
I didn't run in pseudo-distributed mode.
Please check region server log which would give you more clue.
Also, please involve user@ or dev@ so that:
1. you can get more helping hands
2. share your finding with other people.
Have a nice weekend.

Hi Ted,
I’m hoping you can help me – I’m having a problem similar to yours with
HBase (http://search-hadoop.com/m/50Ekr1n36KU1/v=threaded) , I’m using
the Cloudera distro and trying to get Hadoop and HBase running in
pseudo-distributed mode.
Whenever I try to go to the master server webpage (e.g.
http://localhost:60010) it just sits there continually loading.
Could you tell me how you solved the problem where -ROOT- is unable to
come online.
Looking at the logs of the master I see the following:
