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.
> SecureDataNodeStarter does not pick up configuration in hdfs-site.xml

>
> 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.
