Hbase: How to specify hostname for Hbase master

Question

I\'m struggling to setup a Hbase distributed cluster with 2 nodes, one is my machine and one is the VM, using the \"host-only\" Adapter in VirtualBox.

My problem is that

Answer 1

My host file is like

127.0.0.1 localhost

192.168.2.118 shashwat.machine.com shashwat

make your hosts file as following:

127.0.0.1 localhost

For Hadoop

192.168.56.1 master

192.168.56.101 slave

and in hbase conf put following entries :

hbase.rootdir
hdfs://master:9000/hbase


hbase.master
master:60000
The host and port that the HBase master runs at.


hbase.regionserver.port
60020
The host and port that the HBase master runs at.

hbase.cluster.distributed
true


hbase.tmp.dir
/home/cluster/Hadoop/hbase-0.90.4/temp


hbase.zookeeper.quorum
master


dfs.replication
2


hbase.zookeeper.property.clientPort
2181
Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.

If you are using localhost anywhere remove that and replace it with "master" which is name for namenode in your hostfile....

one morething you can do

sudo gedit /etc/hostname

this will open the hostname file bydefault ubuntu will be there so make it master. and restart your system.

For hbase specify in "regionserver" file inside conf dir put these entries

master slave

and restart.everything.
