Sergey Shelukhin updated HBASE-21864:
-------------------------------------
Description:
The state version will ensure we don't have network-related races (e.g. the
one I reported in some other bug -
{code}
RS: send report {R1} ...
M: close R1
RS: I closed R1
M ... receive report {R1}
M: you shouldn't have R1, die
{code}).
Then we can revert the change that removed YouAreDead exception... RS in
incorrect state should be either brought into correct state or killed because
it means some bug; right now of double assignment happens (I found 2 different
cases just this week ;)) master lets RS with incorrect assignment keep it
forever.
