----------------------------------
Summary: Delegation token cannot be fetched and used by different
versions of client
Key: HADOOP-13206
URL: https://issues.apache.org/jira/browse/HADOOP-13206
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.6.1, 2.3.0
Reporter: Zhe Zhang
Assignee: Zhe Zhang
We have observed that an HDFS delegation token fetched by a 2.3.0 client cannot
be used by a 2.6.1 client, and vice versa. Through some debugging I found that
it's a mismatch between the token's {{service}} and the {{service}} of the
filesystem (e.g. {{webhdfs://host.something.com:50070/}}). One would be in
numerical IP address and one would be in non-numerical hostname format.
