Hello, I'm experiencing a weird error while launching Ignite with a custom classloader. It fails to join the cluster with the error reported below. It reports that cannot load the class `DiscoveryDataClusterState` using the classloader `sun.misc.Launcher$AppClassLoader@27716f4`. I think this

I have no idea, I'm not an Spark expert. As far I've understood Spark does not have an api to bind a task to a specific node. The foreachPartition provides an approximation for that, but you can have more than one partition per node resulting in the problem I've described. Cheers, Paolo On

Re: Is it safe to modify the activeJobs and waitingJobs collections in the CollisionContext?

Not sure that load balancing is what is needed in this case. The problem is to make sure that at any time tasks do not consume more resources than the available ones. Thus, a collision spi is the right strategy to handle that I've ended up implementing a custom collision spi delegating the job

Re: IGFS backed by persistence on physical filesystem

This sound interesting. Yes, the idea here is to have a secondary file system storage alternative to Hadoop. My idea is a to have a IgfsSecondaryFileSystem implementation based on java.nio.file.Path. This would make it possible to use a local file system or a NFS storage via the POSIX interface
