I'm not sure what your specific problem is but these are the steps I'd take to
get it up and running:
1. Setup and get hdfs running (verify it by going to http://hdfs-host:50070/)
2. Get zookeeper up and running on 1 host
3. Get hbase up and running in pseudo distributed mode. See:
http://hbase.apache.org/book.html#distributed.
Once you have pseudo distributed mode working, all you have to do is add more nodes and everything
works. Make sure dns / hosts file is setup correctly, if not things wont work. As far as zookeeper
is concerned you would want 1 or 3 zk nodes but not 2. For a cluster your size 1 is plenty. I'd
also update to cdh3u0 as that is the most recent. If you still can't get pseudo distributed mode
working I'd fall back to getting hbase up and running with just a single node running on the local
file system--see http://hbase.apache.org/book.html#quickstart.
Good luck,

And one thing : i have set the hbase-env like this : JAVA_HOME =

Hi all,
I know it's maybe ridiculous but i have problems with HBase installation
in cluster. I will have follow 2-3 tutorials on it but it doesn't work.
Well, first i would like to know if it possible to have 2 servers in
cluster with HBase. I ask this because i have seen that we must have 3
servers for Zookeeper.
Secondly, i don't have really understood the Zookeeper definition ^^
(maybe this one can be the first ^^)
I use HDFS for root.dir but there is a lot of difference between HDFS and
/tmp for example ?
I start "hbase master start" like this and "hbase regionserver start" on
the other node.
I have already insert IP adresses in the regionserver file.
Thirdly, i have question about HDFS : when i start hbase on 1 server it
works (root.dir use HDFS) ; but when i want to see the hadoop system with
localhost:50030 (and of course i have starting all) it doesn't work... There
is a relation ?
If anyone can answer me one of these (or all ^^) thanks to you !
