With 0.18.2 - and unicast disovery

start ES on one machine with unicast, create an index, index one document or even create a single mapping - then shutdown ES, start again - it won't recover the index,



but if you start another *fresh* node with first node as unicast discovery host

it will recover 



now if you kill ES on both nodes, and restart ES on both nodes - ES won't recover

but if you add a third fresh node it will recover
