Hudson commented on HDFS-2528:
------------------------------

Integrated in Hadoop-Hdfs-trunk #857 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/857/])
    HDFS-2528. Webhdfs: set delegation kind to WEBHDFS and add a HDFS token when http requests
are redirected to datanode.

> the following exception is thrown by the datanode when the redirect happens.
> {"RemoteException":{"exception":"IOException","javaClassName":"java.io.IOException","message":"Call

> Interestingly when using ./bin/hadoop with a webhdfs path we are able to cat or tail
a file successfully.
