Dear all,

I am a new learner of HBase. I tried to set up my HBase on a
pseudo-distributed HDFS.

After starting HDFS by running ./start-dfs.sh and ./start-hbase.sh, I
started the HBase shell.

   ./hbase shell

It was started properly. However, when I typed the command, status, as
follows.

   hbase(main):001:0> status

It got the following exception. Since I had very limited experiences to use
HBase, I could not figure out what the problem was.

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in

Could you please give me a hand? Thanks so much!

Is zookeeper running properly? Is it where your shell expects it to
be? Can you access HBase's web ui on port 60010?

Dear Jean-Daniel,

The issue is solved. I think the book in the HBase the Definitive Guide
does not give sufficient descriptions about the pseudo-distributed mode.

Thanks so much!

And what would be missing? It's all open source so this is the moment
where you can forever leave a trace in HBase :)

To stress what JD just said, the HBase book/Ref Guide (i.e., the online
book that is a part of HBase) is open source and the best source of the
material (especially the Troubleshooting chapter) is user experience.

Minor clarification:  "HBase the Definitive Guide" is a great book by
O'Reilly, but not open source.

Hi, J-D,

I just made summary about the experiences to set up a pseudo-distributed
mode HBase.

1) RedHat 9 is not suitable for running HBase and Hadoop. I don't know the
reasons. Now Ubuntu is my choice.

2) After the pseudo-distributed mode of HDFS is configured, it is required
to configure the hbase-env.sh and hbase-site.xml. The book, HBase the
Definitive Guide, does not mentions hbase.env.xml.

3) It should set up JAVA_HOME, HBASE_CLASSPATH and HBASE_MANAGES_ZK. My
hbase-env.sh is as follows.

     export JAVA_HOME=/opt/jdk1.6.1/
     export HBASE_CLASSPATH=/opt/hbase-0.92.0/conf
     export HBASE_OPTS="-XX:+UseConcMarkSweepGC"
     export HBASE_MANAGES_ZK=true

4) When configuring hbase-site.xml, the property,
hbase.cluster.distributed, must be set also. The book, HBase the Definitive
Guide, does not do that either. My hbase-site.xml is as follows.

     <?xml version="1.0"?>
     <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
     <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>
     </configuration>

I am a new user of HBase. Your suggestions are highly appreciated.

Best regards,
Bing
