> 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.
