Stavros Kontopoulos updated SPARK-23790:
----------------------------------------
Description:
This appeared at a customer trying to integrate with a kerberized hdfs cluster.
This is easily fixed with the proposed fix here:
[https://github.com/apache/spark/pull/17333]
The other option is to add the delegation tokens to the current user's UGI as
in here: [https://github.com/apache/spark/pull/17335]. The last fixes the
problem but leads to a failure when someones uses a HadoopRDD because the
latter, uses FileInputFormat to get the splits which calls the local ticket
cache TokenCache.obtainTokensForNamenodes. Eventually this will fail with:
Exception in thread "main"
org.apache.hadoop.ipc.RemoteException(java.io.IOException): Delegation Token
can be issued only with kerberos or web authentication
at
org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getDelegationToken(FSNamesystem.java:5896)
This implies that security mode is SIMPLE and hadoop libs there are not aware
of kerberos.
