Daryn Sharp commented on HDFS-6310:
-----------------------------------
I don't feel the concern with outputting the secret manger state is valid. If
the user has access to the fsimage to run oiv, then they obviously can extract
the state in other ways.
The oiv tool is useful in debugging the state of the fsimage. Selectively
omitting some of the state impedes debugging. For instance, at least a year
ago we discovered that expired tokens were never being purged from the fsimage.
We had clusters whose fsimage contained 2+ years of tokens which added
significant time to NN startup. The problem was evident with the use of oiv.
It concerns me that a documented tool (oiv), with external tools built around
it, is being indiscriminately made incompatible within minor releases.
