> Systemd service is configured (by creating symbolic link - /usr/hdp/current/hadoop-httpfs//usr/lib/systemd/system/hadoop-httpfs.service) as part of yum installation. This service file create /var/run/hadoop-httpfs dir using "httpfs" user. The 'httpfs' doesn't have permission due to that reason service failed after reboot the system

> _[Service]_
> _Type=forking_
> _User=httpfs_
> _Group=hadoop_
> _Restart=on-failure_
> _WorkingDirectory=-/var/run/hadoop-httpfs_
> _...._
> _...._
> _ExecStartPre=/bin/sh -c 'test -d $HTTPFS_RUN || mkdir -p $HTTPFS_RUN'_
> _ExecStartPre=/bin/sh -c 'test -d $HTTPFS_LOG || mkdir -p $HTTPFS_LOG'_
> Hence the above ExecStartPre state create the $HTTPFS_RUN dir as httpfs user
> If it is added with PermissionsStartOnly=true above 'ExecStartPre' line, 'ExecStartPre' executes as a root and 'ExecStart' state is executed as httpfs user.
