Learned Kiji in a few minutes

I had spent a bit time to learn "Introduction to Data Science". Today, I know the Kiji project. Kiji was built on Apache HBase and Apache Hadoop. I thought it's a good idea to learn HBase and Hadoop from it. You can read more about Architecture. So, I spent time a little bit about it. You can read on website, it's easy to install and use.
[surachart@linux01 ~]$ wget
[surachart@linux01 ~]$ tar xzf kiji-bento-*.tar.gz
[surachart@linux01 ~]$ cd kiji-bento-albacore
[surachart@linux01 kiji-bento-albacore]$ source bin/
Set KIJI_HOME=/home/surachart/kiji-bento-albacore/bin/..
Set KIJI_MR_HOME=/home/surachart/kiji-bento-albacore/bin/..
Set SCHEMA_SHELL_HOME=/home/surachart/kiji-bento-albacore/bin/../schema-shell
Set EXPRESS_HOME=/home/surachart/kiji-bento-albacore/bin/../express
Added kiji and kiji-schema-shell binaries to PATH.
Set BENTO_CLUSTER_HOME=/home/surachart/kiji-bento-albacore/cluster/bin/..
Set HADOOP_HOME=/home/surachart/kiji-bento-albacore/cluster/bin/../lib/hadoop-2.0.0-mr1-cdh4.1.2

Set HBASE_CONF_DIR=/home/surachart/kiji-bento-albacore/cluster/bin/../lib/hbase-0.92.1-cdh4.1.2/conf
Added Hadoop, HBase, and bento-cluster binaries to PATH.

Thank you for flying Kiji!
