Description

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.
