> when we install HDF mpack we do the following steps
> yum install ambari-server
> ambari-server install-mpack --mpack=/path/to/hdf-mpack --purge --verbose
> ambari-server setup
> The permissions and ownership for stacks , common-services etc is set
> correctly during ambari-server setup
> Ambari-server daemon is configured to run under user 'slava'. Change this
> setting [y/n] (n)? n
> Adjusting ambari-server permissions and ownership...
> However, to add HDF services to HDP cluster we install the mpack after
> deploying the HDP cluster and hence when running Ambari as non-root and with
> umask = 0027, the permissions and ownerships don't get updated.
> Workaround:
> Re-run ambari-server setup command after installing the HDF mpack but don't
> really make any config changes. Run this step only to update the permissions.
> ambari-server setup -s
