> During startup, JournalNode reads config files that belong to YARN, not HDFS 
> (eg. {{yarn-site.xml}}), if they are present in the Hadoop config dir.
> Ambari's {{File()}} provider creates files at the final location, then sets 
> metadata (ownership and permissions).  This makes the file visible to other 
> processes with possibly the wrong metadata.
> If agent-side parallel execution is enabled, JournalNode may be started 
> concurrently with some YARN component.  JournalNode may encounter a config 
> file that it cannot read, because the file's permissions and owner are still 
> 640 and root, respectively, which causes it to shutdown:
> {noformat}
> ERROR conf.Configuration (Configuration.java:loadResource(2999)) - error 
> parsing conf yarn-site.xml
> java.io.FileNotFoundException: /etc/hadoop/conf/yarn-site.xml (Permission 
> denied)
> {noformat}
