HBase install and performance test

1. download hbase.
   

   [hadoopuser@cent63VM01 app]$ wget http://apache.osuosl.org/hbase/stable/hbase-0.94.2.tar.gz
   

2. untar the file
   

   [hadoopuser@cent63VM01 app]$ tar xvf hbase-0.94.2.tar.gz
   

3. create a soft link for HBase.
   

   [hadoopuser@cent63VM01 app]$ ln -s /hadoop/hbase-0.94.2/ /hbase
   

4. copy sample configuration file.
   

   [hadoopuser@cent63VM01 app]$ cp /hbase/sr/resources/hbase-default.xml /hbase/conf/hbase-site.xml
   

5. Edit hbase-site.xml as below.
   

   sfds
   

6. copy configuration files to all nodes..
   

   sfdsrsync -avz ./hbase-0.94.2 hadoopuser@cent63V4.corp.ybusa.net:/hadoop/
   

7. Zookeeper's port numbers are troublesome. To be simple, I disable the firewall.

   service iptables status
   service save iptables
   service stop iptables
   chkconfig iptables off
   

system-config-firewall open HBase REST port 8080; open port 60000 and 60010 for master. for eegional server open port 60020 and port 60030; for zookeeper, open port 2888, 3888, 2181

check file /etc/hosts


rm -Rf /tmp/hadoop-username  clean data fo

service iptables status
service save iptables
service stop iptables
chkconfig iptables off
