Weiwei Yang commented on YARN-8953:
-----------------------------------
During the testing, I found it is not a wise decision to let RM/NM module
depending on hadoop-yarn-csi module, it would potentially cause dependency
conflicts problems. So in v3 patch I have moved CSI adaptor protocol and
related PB classes to {{hadoop-yarn-api}} and {{hadoop-yarn-common}}, this way
RM/NM only needs to talk to CSI adaptor using YARN protocol, and underneath the
adaptor will take care of the proto-transformation.
And I've added more UTs to verify adaptor server/client side implementations,
and removed fake clients from volume manager. Now it should be able to work
together.
[~sunilg] pls take a look. thanks.

> CSI adaptor is a layer between YARN and CSI driver, it transforms YARN
> internal concepts and boxes them according to CSI protocol. Then forward the
> call to a CSI driver. The adaptor should support both
> controller/node/identity services.
