Jing Zhao commented on HDFS-5898:
---------------------------------
bq. I don't follow how the change in RpcProgramNfs3 is related to this issue.
Yes, I think the change in RpcProgramNfs3 is a regression of HDFS-5913.
One question: the current patch puts the login into
DFSClientCache#getUserGroupInformation, which is called by the load() method of
the loading cache. Thus we will call login() every time we miss the cache.
Should we put the login call into the constructor of RpcProgramNfs3 instead?
> Allow NFS gateway to login/relogin from its kerberos keytab
