Hi
I am newbie working on Hadoop - HBase. I am using Hadoop-0.18.0 and
HBase-0.18.1. There is some problem with using HBase master when HBase
uses HDFS. My Hadoop-site configuration is:
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
And HBase-site configuration is:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
<description>The directory shared by region servers.
</description>
</property>
<property>
<name>hbase.master</name>
<value>localhost:60000</value>
<description>The host and port that the HBase master runs at.
</description>
</property>
<property>
<name>hbase.regionserver</name>
<value>localhost:60020</value>
<description>The host and port a HBase region server runs at.
</description>
</property>
</configuration>
When I try command $ bin/hadoop dfs -ls / I got follwing result:
$ bin/hadoop dfs -ls /
Found 2 items
drwxr-xr-x - HadoopAdmin supergroup 0 2009-03-17 12:22 /hbase
drwxr-xr-x - HadoopAdmin supergroup 0 2009-03-17 12:21 /tmp
But when I use HBase command list in $ bin/hbase shell I got following
exception:

Also when I try to stop HBase with the command $ bin/stop-hbase.sh I got
the message:
no master to stop
When I change my HBase-site configuration to:
<configuration>
<property>
<name>hbase.master</name>
<value>localhost:60000</value>
<description>The host and port that the HBase master runs at.
</description>
</property>
<property>
<name>hbase.regionserver</name>
<value>localhost:60020</value>
<description>The host and port a HBase region server runs at.
</description>
</property>
</configuration>
My master starts working as HBase is now using local file system.
But when I want to use HDFS and change HBase-site configuration then my
master do not starts. Please tell me how I should configure so my HBase
master starts working and HBase use HDFS. Hope you people help me in
this.
