Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip
Date Thu, 15 Sep 2011 22:25:10 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13105733#comment-13105733

Jitendra Nath Pandey commented on HADOOP-7510:

It would be good to put on the jira the reasons behind some of the design choices in NetUtils.java
1) The usage of ResolverConfiguration.
2) The different handling of hosts with a dot in the end and those containing dot in the middle.

HftpFileSystem.java: Why was getCanonicalServiceName removed?

  The change of createRPCNamenode call to createNamenode changes retry policy and exception
policy. This change is not required.

  The patch will change a bit with latest commit in HADOOP-7625, the service is not being
set in DFS anymore.

  What is the need to change from proxy to JobClient?

> Tokens currently store the ip:port of the remote server.  This precludes tokens from
being used after a host's ip is changed.  Tokens should store the hostname used to make the
RPC connection.  This will enable new processes to use their existing tokens.
