Chris Trezzo updated YARN-2180:
-------------------------------
Attachment: YARN-2180-trunk-v4.patch
[~kasha] [~vinodkv] [~sjlee0]
Attached is v4. Here are some significant changes:
1. Bootstrapping and old SCMContext logic is now moved to the serviceInit of
the in-memory store.
2. SCMStore interface is annotated properly with private and evolving.
3. Eviction logic of a shared cache resource has moved to the SCMStore
implementation. The isResourceEvictable method has been added to the SCMStore
interface to expose this.
4. There is a new configuration class (InMemorySCMStoreConfiguration) that
allows for InMemorySCMStore implementation specific configuration.
5. Javadoc rework and method name refactoring so that items and their
references in the shared cache are referred to as shared cache resources and
shared cache resource references.
6. Various other refactors to address comments.
