Tablet has no consensus state
Using Kudu 1.2, I'm trying to add a range partition to a table, and it
appears to succeeded (Alter() returns Status::OK()), but I see this in
kudu-master.WARNING:
W0306 21:03:42.175981 54035 catalog_manager.cc:2394] Unable to reset TS
proxy: Not found: No leader found: Tablet b9aecb10e5e844b885a753c615432df9
has no consensus state

table request: Not found: Failed to reset TS proxy: No leader found: Tablet
b9aecb10e5e844b885a753c615432df9 has no consensus state
What does this mean and what might I have done wrong?

I was looking at ResetTSProxy() in the context of AddServer async task
yesterday, it is possible that the missing leader transient error case
handling could be racy. Before providing the accurate problem description,
I will try to repro the issue with a test next week and file/fix a JIRA if
there is a genuine race.

Moving thread to dev@ for a follow-up question: can we make this error
message clearer, if this is an expected behavior? I'm a little confused as
to what sequence of events leads to this, though.

Hi Paul
That somewhat misleading message means that that particular tablet doesn't have (and never had) a leader.
It might be a transient error, the master will continue to try the alter but you might want to check if you have crashed servers and/or under-replicated tablets.
