Aaron T. Myers commented on HDFS-5898:
--------------------------------------
Hi Abin, thanks a lot for working on this. A few quick comments:
# I don't follow how the change in RpcProgramNfs3 is related to this issue. Did
that perhaps sneak in to this patch accidentally? Or is it somehow related and
I'm completely missing it?
# We should probably put the new constants in DFSConfigKeys.java instead of
Nfs3.java. Also, entries for them should also be added to hdfs-default.xml to
document them.
# Did you test this with a long-running NFS gateway against a Kerberized
cluster? i.e. longer than the ticket lifetime granted by default from the KDC?
The reason I ask is because I see no "reloginFromKeytab" anywhere in the patch,
which I would expect to be necessary.
# I don't think the included tests actually exercises the new functionality. I
tried just applying that portion of the patch and it passed without issue. To
write an automated test for this, you'll probably have to use the MiniKdc. Or,
you could test this manually against a real cluster/KDC and report the findings
here.
