Dmitriy, It is not a firewall issue. However, the hardware crash has something to do with it probably.
In that direction - can one expect a crash of one node (out of 5) housing a few partitioned caches to affect the availability of all the caches? The strange thing is visor was able to show them all but acquiring them through a Scala app using getOrCreateCache() just hung. I ended up "rigging" visor with a capability to dump cache -scan results to a file - I was able to salvage all my data and then I restarted the cluster. Certainly pretty clumsy ;) Ognen On Tue, May 12, 2015 at 1:28 PM, Dmitriy Setrakyan <[email protected]> wrote: > Ognen, > > It sounds to me like this is the same issue you had recently with the cloud > node crashing due to hardware failure.
