Dear Jimmy, I am a new user of HBase. My experiences in HBase and Hadoop is very limited. I just tried to follow some books, such as Hadoop/HBase the Definitive Guide. However, I still got some problems.
What I am trying to do is just to set up a pseudo distributed HBase environment on a single node. After that, I will start my system programming in Java. I hope I could deploy the system in fully distributed mode when my system is done. So what I am configuring is very simple. Do I need to set up the zookeeper port in hbase-site.xml? Thanks so much!
