DataNode appears to require DNS name resolution as opposed to direct ip mapping -------------------------------------------------------------------------------
Key: HADOOP-685 URL: http://issues.apache.org/jira/browse/HADOOP-685 Project: Hadoop Issue Type: Improvement Components: dfs Environment: osx, ubuntu 6.10b Reporter: James Todd Priority: Minor DataNode appears to require DNS resolution of nodes via the class org.apache.hadoop.net.DNS as opposed being able to use a specified ip. as an example, i was not able to set up more then one instance of dfs datanodes on one box using loopback w/ varying ports since DataNode resolved the ip of 127.0.0.1 to be "foo.bar" which was then mapped to the dhcp allocated ip of 192.168.0.***, which was not addressable by the rest of the dfs cluster (namely namenode). while this example is trivial one should be able to use the very same process yet change only the ip's of the nodes and have things work as expected. it would be nice to not always require nds resolution. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
