All Known Implementing Classes:

public interface HadoopFileSystemFactory
extends Serializable

Factory for Hadoop FileSystem used by IgniteHadoopIgfsSecondaryFileSystem.

get(String) method will be used whenever a call to a target FileSystem is required.

It is implementation dependent whether to rely on built-in Hadoop file system cache, implement own caching facility or doesn't cache file systems at all.

Concrete factory may implement LifecycleAware interface. In this case start and stop callbacks will be performed by Ignite. You may want to implement some initialization or cleanup there.
