Install

Download tarball form http://mirrors.cnnic.cn/apache/hbase/hbase-0.98.0/

#tar -xzvf  hbase-0.98.0-hadoop2-bin.tar.gz 
#cd hbase-0.98.0-hadoop2

Configure

Note:the following conf is suited to fully-distributed mode not standalone mode.

 

-------system env ----

In the file /etc/security/limits.conf add a line like:

hadoop  -       nofile  32768

Replace hadoop with whatever user is running Hadoop and HBase. If you have separate users, you will need 2 entries, one for each user. In the same file set nproc hard and soft limits. For example:

hadoop soft/hard nproc 32000

In the file /etc/pam.d/common-session add as the last line in the file:

session required  pam_limits.so

Don't forget to log out and back in again for the changes to take effect!

 

-------conf/hbase-env.sh-----

export JAVA_HOME=/usr/lib/jvm/java-7-oracle

export HBASE_MANAGES_ZK=false

//To point HBase at an existing ZooKeeper cluster, one that is not managed by HBase. Next set ensemble locations and client port, if non-standard, in hbase-site.xml, or add a suitably configured zoo.cfg to HBase's CLASSPATH.

A distributed Apache HBase installation depends on a running ZooKeeper cluster
