Re: RegionServer unable to connect to master
Is that correct?

$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       obelix105.local xx.yy.net    obelix105
192.168.245.1   obelix.local

In regionserver list you have obelix105.local

wich point to 127.0.1.1. Should it not bt 192.168.245.1 instead?
