gaborgsomogyi opened a new pull request #23698: [SPARK-26766][CORE] Remove the list of filesystems from HadoopDelegationTokenProvider.obtainDelegationTokens
URL: https://github.com/apache/spark/pull/23698
 
 
   ## What changes were proposed in this pull request?
   
   Delegation token providers interface now has a parameter `fileSystems` but this is needed only for `HadoopFSDelegationTokenProvider`.
   
   In this PR I've addressed this issue in the following way:
   * Removed `fileSystems` parameter from `HadoopDelegationTokenProvider`
   * Moved `YarnSparkHadoopUtil.hadoopFSsToAccess` into `HadoopFSDelegationTokenProvider`
   * Moved `spark.yarn.stagingDir` into core
   * Moved `spark.yern.access.namenodes` into core and renamed to `spark.kerberos.access.namenodes`
   * Moved `spark.yarn.access.hadoopFileSystems` into core and renamed to `spark.kerberos.access.hadoopFileSystems`
   
   ## How was this patch tested?
   
   Existing unit tests.
