Nutch 2.1 cannot setup in Mac

Question

Trying to set up the new Nutch 2.1 in local environments. With the fresh download, then "ant build". Following the document from wiki http://wiki.apache.org/nutch/Nutch2Tutorial however, it seems that no luck

I got the following errors:

Your help is highly appreciated. thanks

I have the same problem. I installed HBase 0.94.3 , ZooKeeper 3.4.5 , Nutch 2.1 . After HBase & ZooKeeper successfully started, I run bin/nutch inject result/urls.txt. (the urls.txt contains URLs to inject.) same exception encountered. I'm using Mac OS X 10.7.5 — Raptor
I found the resolution for this question after checked the logs carefully. Check your regionservers under hbase/conf and /etc/hosts to see if they are matched. — Pandaski

Caused by: org.apache.hadoop.hbase.MasterNotRunningException

this indicates that the clsuter setup is not done correctly. The nutch tutorial page mentions this:

Install and configure HBase. You can get it here (N.B. Gora 0.2 uses HBase 0.90.4, however the setup is known to work with more recent versions of the HBase 0.90.x branch)

Have you performed this step correctly ?
