Description

When submit sample MapReduce job WordCount which read/write path under encryption zone on HDFS Federation in security mode to YARN, task throws exception as below:

The main reason is before submit job in security mode, we need to collect delegation tokens include delegation token for NameNode and KMS firstly. IF on HDFS Federation, all delegation tokens for NameNode can collection correctly BUT delegation token for KMS not collect reference FileSystem#addDelegationTokens -> FileSystem#collectDelegationTokens, so when launch task it fails because KMS token not pass to through ResourceManager as exception shows GSSException: No valid credentials provided.
