Daryn Sharp commented on MAPREDUCE-3639: ---------------------------------------- I think you can use {{NetUtils.addStaticResolution}} to dummy out the lookups of "host". bq. That check should not be present. getCanonicalServiceName will return null for filesystems like viewfs. With that additional check - TokenCache will not get tokens for the underlying filesystems. Sigh, that's right, and one of the things I was trying to fix in an alt patch. The view fs token caching is getting quite murky, but this at least makes it work better, so +1... > TokenCache likely broken for FileSystems which don't issue delegation tokens > ---------------------------------------------------------------------------- > > Key: MAPREDUCE-3639 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3639 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.0 > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Priority: Blocker > Attachments: MR3639.txt > > > Ref HADOOP-7963. -- This message is automatically generated by JIRA.
