I'm using Hbase 0.94.8.
I restarted that specific RS and the HMaster but without any luck. The logs doesn't contain any errors.
Any ideas? Thanks
Could you please take a look at your master UI and let me know if you see any regions stuck in transition? If so, can you please post a link to a screen shot of it? Also, can you bounce the RS and then send pastebin to the RS logs for us as well?
I was out of office the last two days...
In the end I solved the issue.
There was not regions in transitions in the master UI and the numberOfOnlineRegion was 0 for that RS.
The problem was with the settings from /etc/hosts.
Somehow in the fist line, that with 127.0.0.1, appeard the DNS of that RS. I deleted it and now its working.
