set the namenode public IP address in amazon EC2?
Hi,

I'm trying to configure the Namenode with  a public IP in amazon EC2. The
service always get the host private IP, and not the public one. How can I
set the namenode public IP address?

Here are my configuration files:

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

<!-- Put site-specific property overrides in this file. -->
<configuration>
<property> <name>dfs.replication</name> <value>3</value> </property>
<property> <name>fs.default.name</name> <value>hdfs://
ec2-46-XXXXXX.eu-west-1.compute.amazonaws.com:54310</value> </property>
<property> <name>dfs.data.dir</name>
<value>/home/ubuntu/MRtmp/dfs/data</value> </property>
<property> <name>dfs.permissions</name><value>false</value></property>
<property>
<name>dfs.permissions.enabled</name><value>false</value></property>
<property><name>dfs.datanode.data.dir.perm</name><value>777</value></property>
</configuration>

$ cat core-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<!-- Put site-specific property overrides in this file. -->

<configuration>
<property><name>hadoop.tmp.dir</name><value>/home/ubuntu/MRtmp/dir/hadoop-${
user.name}</value></property>
<property><name>hadoop.backup.files</name><value>true</value></property>
<property><name>hadoop.tmp.bkp.dir</name><value>/home/ubuntu/MRtmp/backup/dir/hadoop-${
user.name}</value></property>
<property><name>fs.default.name</name><value>hdfs://
ec2-46-XXXXXXXXXXX.eu-west-1.compute.amazonaws.com:54310</value></property>
<property><name>hadoop.security.authentication</name><value>simple</value></property>
<property><name>hadoop.security.authorization</name><value>false</value></property>
</configuration>
