“very easy to install and setup. I am able to run Spark v1.5 cluster on it, but very slow
1/ beware that it only support LAN but not WIFI (difficult to create bridge)
2/ you can have 1 to 4 Pi0 installed on it
3/ found a problem on shutdown them, it just hang without disconnection. no idea why
4/ the HAT provides the power and USB connects them. I replaced the original USB with my own because it is longer”
“Works exactly as I'd hoped - the hardest part is getting hold of enough Pi Zeroes! I've used the supplied images to flash the SD cards and then installed Docker, everything so far 'just works'. The amazing part is being able to connect directly to any of the Zeroes from my laptop using a name such as p1..p4.local without having to mess with network settings etc - it's just magic! Thanks for a great product! :-)”
