Vladimir Ozerov commented on IGNITE-3625:
-----------------------------------------
I still do not quite understand why do we need some magic in getters and
setter. Can we do the following?
1) If cache name is set explicitly, then use it.
2) If not, then pick relevant cache configuration, convert cache name, and add
this cache to startup list.
> IGFS: Use common naming for IGFS meta and data caches.

> URL: https://issues.apache.org/jira/browse/IGNITE-3625
> Project: Ignite
> Issue Type: Task
> Components: IGFS
> Affects Versions: 1.6
> Reporter: Vladimir Ozerov
> Assignee: Taras Ledkov
> Fix For: 2.0
>
>
> Currently IGFS is configured by passing names of two caches: meta and data.
> See {{FileSystemConfiguration.metaCacheName}} and
> {{FileSystemConfiguration.dataCacheName}}.
> These two caches are considered internal then and are not accessible for the
> user.
> We need to do the following during node startup:
> 1) If certain cache is configured as meta or data cache for multiple IGFS-es,
> or if it is configured as both meta and data cache for a single IGFS, then
> throw an exception.
> Relevant code pieces:
> {{IgfsProcessor.validateLocalIgfsConfigurations}}
> {{IgfsProcessorSelfTest}}.
> 2) During node startup change the name of this cache to
> {{igfs-IGFS_NAME-meta}} or {{igfs-IGFS_NAME-data}}. Change must be performed
> both inside IGFS config and cache config.
> Relevant code pieces:
> {{CacheConfiguration.name}}
> {{FileSystemConfiguration.metaCacheName}}
> {{FileSystemConfiguration.dataCacheName}}
> {{IgfsUtils.prepareCacheConfiguration}} - where change will be done.
> 3) If any of new names caches with any other cache name, an exception should
> be thrown. The most simple way: throw an exception if user-configured cache
> name starts with {{igfs-}} and ends with {{-meta}} or {{-data}}.
> Relevant code pieces:
> {{IgniteNamedInstance.initializeDefaultCacheConfiguration}}.
