FAQ
Hi all:
I found that I can set more than one dfs.name.dir in hadoop-site.xml
like below:
<property>
<name>dfs.name.dir</name>
<value>/opt/hadoop/dfs/name1</value>
<value>/opt/..../name2</value>
<description>Determines where on the local filesystem the NDFS name
node
should store the name table.</description>
</property>

Does this mean I have a backup of my namenode info? Or this is for some
other special reasons?

Best Regards,

Jianglei
