Sandy Ryza commented on MAPREDUCE-5379:
---------------------------------------
[~revans2], TokenCache already has logic for traversing the FS hierarchy and
getting all the delegation tokens. Could we not do something like this?
[~daryn], I was thinking of token ID as the token identifier. HDFS-4680 seeks
to audit-log token identifiers with FS operations. If an MR job were to expose
its token identifiers as well, then we would be able to associate the FS
operations it performed with it. Right?
