My mistake. In the Cloudera Manager every service, including spark is on green. reply | permalink Fernando Iwamoto - Plannej Iam new to HBASE too, but I had same problem long time ago and I dont remember how i fixed, I will keep troubleshooting This is the log:2011-12-15 13:46:43,415 INFOorg.apache.hadoop.hbase.regionserver.HRegionServer: Attempting connect toMaster server at localhost:600002011-12-15 13:47:43,473 WARNorg.apache.hadoop.hbase.regionserver.HRegionServer: Unable to connect tomaster.

I think the HMaster should startat master:60000. "master" is the hosts where JobTracker runs.I am using hbase 0.90.3 and zookeeper 3.3.4. I really appreciate that. Yes, i will be careful next time. weblink So, please share with me how you tackle the problem!
