vanzin commented on issue #26493: [SPARK-29574][K8S] Add SPARK_DIST_CLASSPATH 
to the executor class path
URL: https://github.com/apache/spark/pull/26493#issuecomment-554526940
 
 
   I don't see any code in the k8s backend that's actually propagating 
`SPARK_DIST_CLASSPATH` to the pods. That's generally propagated e.g. from 
`spark-env.sh` when you use YARN. Although I can see how that's a bit different 
on k8s (since the pod and launch node may be really different).
   
   Anyway, it seems that at the very least `hadoop-provided.md` needs to be 
updated for this case, since the instructions there don't work for k8s as far 
as I can tell.
