In your hadoop-site.xml file in config set the following variable:
<property>
<name>dfs.datanode.dns.interface</name>
<value>default</value>
<description>The name of the Network Interface from which a data node
should
report its IP address.
</description>
</property>
Change default to the name of your interface (network card), usually
eth0, eth1, etc.

Hi,
The machines I am using each has multiple network cards, and hence
multiple IP addresses. Some of them look like a default IP. However, I
wish to use some other IPs, and tried to modify the hadoop-site.xml,
masters, and slaves files. But it looks that the IP still jumps to the
default ones when hadoop runs. Does anyone have an idea how I could
possibly make it work? Thank you!
