Subject [jira] [Commented] (HADOOP-12847) hadoop daemonlog should support https and SPNEGO for Kerberized cluster
Date Tue, 26 Apr 2016 22:12:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15259046#comment-15259046

Yongjun Zhang commented on HADOOP-12847:

Hi [~jojochuang],

Thanks for reporting and working this issue!

A few quick comments:
1. Make sure the default behavior is the same as without passing the new switches.
2. I think it's better to move the param parsing part in doGetLevel to the dedicated param
parsing method
3. Make "http" "https" contant, such as {{PROTOCOL_HTTP}}, {{PROTOCOL_HTTPS}}, and use them
at the currently hardcoded places
4. I expect to see the following test result, would you please test it out?

||SSL-enabled||Kerberized||Test Output With -http||Test Output With -https||

> {{hadoop daemonlog}} is a simple, yet useful tool for debugging.
> However, it does not support https, nor does it support a Kerberized Hadoop cluster.
> Using {{AuthenticatedURL}}, it will be able to support SPNEGO negotiation with a Kerberized
name node web ui. It will also fall back to simple authentication if the cluster is not Kerberized.
