Not sure what the whole error is, but you can always alternatively try this -
<property>
  <name>fs.default.name</name>
  <value>s3://BUCKET</value>
</property>

<property>
  <name>fs.s3.awsAccessKeyId</name>
  <value>ID</value>
</property>

<property>
  <name>fs.s3.awsSecretAccessKey</name>
  <value>SECRET</value>
</property>

And I am not sure what is the base hadoop version on S3, but possibly if S3 
wiki is correct try updating conf/hadoop-site.xml

Hi all,
    I tried to run my hadoop program on S3 by following this wiki page:
http://wiki.apache.org/hadoop/AmazonS3
    I configured the core-site.xml by adding

<property>
  <name>fs.default.name</name>
  <value>s3://ID:sec...@bucket</value>
</property>

    and I specified the accesskey and secretkey by using the URI
format:s3://ID:sec...@bucket

however, it fails and datanodes reports:

NumberFormatException....
...

Is this the right way to config hadoop running on s3? if so, whats the
problem?
