Dear all,

After searching on the Web and asking for help from friends, I noticed that
the pseudo distributed configuration in the book, HBase the Definitive
Guide, was not complete. Now the ZooKeeper related exception is fixed.
However, I got another error when typing "status" in the HBase shell.

    ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7
Times

I am trying to fix it myself. Your help is highly appreciated.

Thanks so much!
Bing Li

What's your hbase.zookeeper.quorom configuration?   You can check out this
quick start guide:

http://hbase.apache.org/book/quickstart.html

Thanks,
Jimmy

Dear Jimmy,

Thanks so much for your reply!

I didn't set up the zookeeper.quorom. After getting your email, I made a
change. Now my hbase-site.xml is as follows.

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>localhost</value>
  </property>
</configuration>

The previous error is still existed. I feel weird why HBase developers
cannot provide a reliable description about their work.

Best,
Bing

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!

Best,
Bing

In this case, you may just use the standalone mode.  You can follow the
quick start step by step.

The default zookeeper port is 2181, you don't need to configure it.

Dear Jimmy,

I configured the standalone mode successfully. But I wonder why the pseudo
distributed one does work.

I checked in logs and got the following exceptions. Does the information
give you some hints?

Thanks so much for your help again!

Bing

Which port does your HDFS listen to? It is not 9000, right?

<name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>

You need to fix this and make sure your HDFS is working, for example,
the following command should work for you.

hadoop fs -ls /

Dear Jimmy,

Thanks so much for your instant reply!

My hbase-site.xml is like the following.

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
  <property>
    <name>hbase.master</name>
    <value>localhost:60000</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>localhost</value>
  </property>

When I run hadoop fs -ls /, the directories and files under the linux root
are displayed.

Best,
Bing
