Key: HDFS-2473 URL: https://issues.apache.org/jira/browse/HDFS-2473 Project: Hadoop HDFS Issue Type: Bug Components: hdfs client Affects Versions: 0.20.205.0 Reporter: Daryn Sharp Priority: Critical Retrieving tokens from an insecure cluster throws an NPE. This prevents copies from insecure to secure clusters. The problem is in {{DFSClient.getDelegationToken()}}. It attempts to set the service and log the token w/o a null check. FetchDT will also throw exceptions when fetching tokens from an insecure cluster. -- This message is automatically generated by JIRA.
