Allen Wittenauer commented on HADOOP-10322:
-------------------------------------------
I have a feeling I didn't ask my question properly. If I have keytab with:
{code}
HTTP/hostname1@REALM
hdfs/hostname1@REALM
HTTP/hostname2@REALM
hdfs/hostname2@REALM
{code}
inside of it, we'll do the correct thing? I'm just concerned about surprises
callers may be faced with more complex (but legal!) setups.
