Sky,
Yes, every request to a Tablet needs to be authorized. The rabbit hole
(complexity) goes a bit further which, I believe, could result in this
value being even higher than this.
This in mind: what is your end goal? What are you trying to figure out?
Authorizations are cached by Accumulo which greatly reduce any
performance impact of Accumulo having to do checks like these in the
face of parallelism.

Hi,
I am using Accumulo 1.7.2 and I create a table with 31 splits. When I do
a table scan via Accumulo shell (scan -st -t mytable), I see 33 requests
to get authorizations for the user doing the scan. My understanding is
there will be an initial request to fetch current user's authorizations,
the default value. Then for each tablet, there will be a authorization
validation.
Then I pass authorizations to the command. i.e., scan -st -t mytabe -s
1. I still see 33 requests while I expect 32 as there is no need to get
current user's authorizations first. So it seems there is something
wrong with my assumptions.
Why do I see multiple requests for user authorizations? Does it relate
to the number of tablets?
Thanks,
Sky
