Subject [jira] [Commented] (HDFS-5876) SecureDataNodeStarter does not pick up configuration in hdfs-site.xml
Date Tue, 04 Feb 2014 19:28:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5876?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13891061#comment-13891061

Haohui Mai commented on HDFS-5876:

I've started the DN in secure mode, and I've specified dfs.http.policy in hdfs-site.xml.

The DN successfully picked up the configuration and worked as expected.

> The current implementation of {{SecureDataNodeStarter}} does not guarantee that configuration
in hdfs-site.xml is picked up.
> The configuration in hdfs-site.xml will be only picked up when the JVM loads the {{HdfsConfiguration}}
class. The {{HdfsConfiguration}} class might remain uninitialized when {{SecureDataNodeStarter}}
starts to run. As a result, configuration like {{dfs.http.policy}} would has no effects when
this bug manifests.
