             Summary: IGFS: Simplify meta and data cache configuration.
                 Key: IGNITE-3529
                 URL: https://issues.apache.org/jira/browse/IGNITE-3529
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.6
            Reporter: Vladimir Ozerov
             Fix For: 2.0


Currently IGFS configuration is rather complex because user have to manually do the following:
1) Configure meta cache
2) Configure data cache 
3) Wire them up with IGFS through {{FileSystemConfiguration.*CacheName}} properties. 

Instead, I propose to do the following:
1) Add two properties directly to {{FileSystemConfiguration}}:
- dataCacheConfiguration
- metaCacheConfiguration

2) Names of these cache will be ignored and overwritten with cache name unique to concrete IGFS . E.g. *_data and *_meta, where * is IGFS name.

3) *THE MOST IMPORTANT THING* - provide sensible defaults. 

This way normally user will not bother about cache config at all. He will only need to add IGFS config bean and set it's name.
