Oleg Zhurakousky commented on TEZ-1193:
---------------------------------------
My only comment is; I would remove _DEV, since its not for DEV purposes at all.
In fact I don't see many developers who will write Tez apps to ever rely on
'tez.lib.uris' once the framework support for transparent classpath management
is there. We were actually discussing a common YARN resource repository in
HDFS. All apps could be aware of such repository, so classpath propagation does
not have to be duplicated by many apps and so on.
> Make 'tez.lib.uris' dependency optional

> Hadoop/YARN provides a mechanism to setup a runtime classpath of Tez/YARN job
> through LocalResources. Tez exposes setting of LocalResources through
> AMConfiguration and Vertex thuis allowing AM and ACs have its independent
> classpath which can include Tez (depending on how Tez job is written). This
> means that setting _tez.lib.uris_ and installing Tez all together should be
> optional since its libraries could be easily propagated during job submission.
> It also ensures that the Tez libraries that were used during build are the
> same that are used during the runtime.
