Daryn Sharp commented on HDFS-3905:
-----------------------------------

I don't think so.  The issue is specific to KSSL, which I don't think 
trunk/branch-2 supports?
                
> Secure cluster cannot use hftp to an insecure cluster

> HDFS-3873 fixed the case where all exceptions acquiring tokens for hftp were 
> ignored.  Jobs would be submitted sans tokens, and then the tasks would 
> eventually all fail trying to get the missing token.  HDFS-3873 made jobs 
> fail to submit if the remote cluster is secure.
> Unfortunately it regressed the ability for a secure cluster to access an 
> insecure cluster over hftp.  The issue is unique to 23 due to KSSL.
