Saisai Shao updated SPARK-19021:
--------------------------------
Priority: Minor (was: Major)
> Generailize HDFSCredentialProvider to support non HDFS security FS
> ------------------------------------------------------------------
>
> Key: SPARK-19021
> URL: https://issues.apache.org/jira/browse/SPARK-19021
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 2.1.0
> Reporter: Saisai Shao
> Priority: Minor
>
> Currently Spark can only get token renewal interval from security HDFS
> (hdfs://), if Spark runs with other security file systems like webHDFS
> (webhdfs://), wasb (wasb://), ADLS, it will ignore these tokens and not get
> token renewal intervals from these tokens. These will make Spark unable to
> work with these security clusters. So instead of only checking HDFS token, we
> should generalize to support different {{DelegationTokenIdentifier}}.
> This is a follow-up work of SPARK-18840.
