Íñigo Goiri commented on HDFS-13972:
------------------------------------
I was thinking if there was some counter we could check to see what user
executed commands.
However, the RPC side doesn't have it available.
Not sure how to check for this easily...
How easy to make the stub for the getDatanodeReport() as a cache?
No need to implement the full caching but just checking for it.
In the follow-up we actually track that.
Actually, isn't the RouterRpcServer already caching it?
Can we rely on it?
