Dear all,
I am a new user of HDFS. The default Data/Name directory is /tmp. I would
like to change it. The hdfs-site.xml is updated as follows.
<property>
<name>dfs.replication</name>
<value>1</value>
<description>The actual number of replications can be specified when
the file is created.</description>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/bing/GreatFreeLabs/Hadoop/FS</value>
</property>
<property>
<name>dfs.name.dir</name>
<value>${hadoop.tmp.dir}/dfs/name/</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>${hadoop.tmp.dir}/dfs/data/</value>
</property>
But when formatting by running the following command, I was asked to format
the /tmp. Why?
$ hadoop namenode -format
Re-format filesystem in /tmp/hadoop-libing/dfs/name ? (Y or N) N
Because the updated name node is not formatted, the name node cannot be
started.
How to solve the problem? Thanks so much!
Best regards,
Bing
