> HDFS delegation token not found in cache errors seen on Observer NameNodes
> --------------------------------------------------------------------------
>
> Key: HDFS-17964
> URL: https://issues.apache.org/jira/browse/HDFS-17964
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Reporter: Aleksei Ieshin
> Priority: Major
> Labels: pull-request-available
>
> Observer NameNodes fatally reject delegation tokens they have not yet tailed.
> *DelegationTokenSecretManager.retriableRetrievePassword* and
> *FSNamesystem.verifyToken* wrap *InvalidToken* in a *RetriableException* only
> when *inTransitionToActive()*. An observer in steady state never is, so a
> token the active issued moments ago fails with
> {code:java}
> InvalidToken: Token for real user: <user>, can't be found in cache
> {code}
> HDFS-5322 added that guard in 2.3.0, before Observer NameNodes existed
> (HDFS-12943). Widening it to cover observers fixes both paths.
> h6. Details:
> The common trigger is *WebHDFS* *op=OPEN*, the one operation with a second
> hop: the NameNode redirects to a DataNode, and that DataNode validates the
> token against a NameNode chosen by its own *ConfiguredFailoverProxyProvider*.
> Nothing the client configures influences that choice, so in a three-NameNode
> HA setup with one observer a substantial fraction of reads land on the
> observer and fail with HTTP 403.
>
>
>
>
>
> Fix: treat an observer as possibly behind on tailing at both sites, so a
> failed lookup yields *RetriableException*. Callers already handle it - that
> is what HDFS-5322 relies on. No config, no new mechanism.
