Subject [jira] [Commented] (YARN-2179) Initial cache manager structure and context
Date Wed, 17 Sep 2014 21:33:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138021#comment-14138021
] 

Karthik Kambatla commented on YARN-2179:
----------------------------------------

bq. One approach would be to move the shared cache project back into the RM project.
That should work. I am okay with leaving the patch as is for now and move modules when we
are embedding SCM in the RM.

bq. Would it make more sense to leverage getFinalApplicationStatus() instead of getYarnApplicationState()?
Sounds reasonable.

> Implement the initial shared cache manager structure and context. The SCMContext will
be used by a number of manager services (i.e. the backing store and the cleaner service).
The AppChecker is used to gather the currently running applications on SCM startup (necessary
for an scm that is backed by an in-memory store).
