Subject [jira] [Commented] (HADOOP-8855) SSL-based image transfer does not work when Kerberos is disabled
Date Wed, 26 Sep 2012 22:49:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13464261#comment-13464261

Andy Isaacson commented on HADOOP-8855:

Further to the above, I've also verified that using the patched JAR, the 2NN is able to retrieve
the fsimage from the NN with config

Thanks for the fix, Todd.

>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: security
>    Affects Versions: 3.0.0, 2.0.2-alpha
>            Reporter: Todd Lipcon
>            Assignee: Todd Lipcon
>            Priority: Minor

> In SecurityUtil.openSecureHttpConnection, we first check {{UserGroupInformation.isSecurityEnabled()}}.
However, this only checks the kerberos config, which is independent of {{hadoop.ssl.enabled}}.
Instead, we should check {{HttpConfig.isSecure()}}.
