Jason Lowe commented on YARN-8383:
----------------------------------
bq. I think adding dependencies share/hadoop/yarn/lib is right way to fix. But
this change going to bring back YARN-6628 which will become compatible issue
for older jobs right?
I'm not proposing adding the dependency back for 2.8. The attached patch
shades even more than we did before, so if anything we're removing dependencies
from an app's point of view if this patch goes into 2.8.
Instead I was proposing adding the dependency back in for branch-2 and
branch-2.9, since the jackson dependency is already there in those release
lines due to HDFS pulling it in. On those two branches shading YARN's jackson
dependency isn't buying us anything from an app's perspective.
