> Job submit failure and Task executes failure if Standby NameNode domain name can not
resolved on HDFS HA with DelegationToken feature.
> This issue is triggered when create {{ConfiguredFailoverProxyProvider}} instance which
invoke {{HAUtil.cloneDelegationTokenForLogicalUri}} in HA mode with Security. Since in HDFS
HA mode UGI need include separate token for each NameNode in order to dealing with Active-Standby
switch, the double tokens' content is same of course. 
> However when #setTokenService in {{HAUtil.cloneDelegationTokenForLogicalUri}} it checks
whether the address of NameNode has been resolved or not, if Not, throw #IllegalArgumentException
upon, then job submitter/ task executor fail.
> HDFS-8068 and HADOOP-12125 try to fix it, but I don't think the two tickets resolve completely.
> Another questions many guys consider is why NameNode domain name can not resolve? I think
there are many scenarios, for instance node replace when meet fault, and refresh DNS sometimes.
Anyway, Standby NameNode failure should not impact Hadoop cluster stability in my opinion.
