Hi, everyone,
When I access insecure hdfs cluster, call getDelegationToken interface, then
namenode give me a token anyway, but when I send a token cancel request, it
report the error below,
It seem wired, why not return NULL since the cluster is insecure and now that
the token has been given, why cancelling it will cause error. Is there some
ways to avoid it?
I am working on many clusters with same application, which cannot distinguish
bettween the secure and insecure. Any hint will be very appreciated.
