Jayush Luniya commented on AMBARI-10023:
----------------------------------------
[~vijikarthi]
Thanks for taking this initiative.
I just wanted to comment on point 2.a in the design document
{noformat}
All file system service implementation should extend from common/HCFS service
layer.
a) HDFS service implementation should extend from common services/HCFS service.
(Note, here the common/hdfs service is extending from common/hcfs service. This
is a new
capability that is not implemented in current Ambari design.)
{noformat}
The stack inheritence actually does support a service in common-services to
inherit from another service in common services. So you can have
common-services/HDFS/1.0 inherit from common-services/HCFS/1.0. In
common-services/HDFS/1.0/metainfo.xml you need to add
{noformat}
<extends>common-services/HCFS/1.0</extends>
{noformat}
> Ambari framework to support adding any new hadoop compatible file system at
> ease
