Weiwei Yang commented on YARN-9057:
-----------------------------------
Thanks [~eyang], [[email protected]]. Let me revisit this shading again, I was
trying to use such shading to avoid dependency conflicts, but it seems to
create more problems than the ones it fixed. In CSI deployment, we can also
wrap up them as individual containers and launch as a simple YRAN service app.
In that case, the shading is no longer needed. Will try and upload a patch
today.
Thanks.
