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
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:
