Subject [jira] [Commented] (YARN-956) [YARN-321] Add History Store interface and testable in-memory HistoryStorage
Date Wed, 31 Jul 2013 23:19:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13725818#comment-13725818

Zhijie Shen commented on YARN-956:
----------------------------------

bq. Can you also write a test for InMemory storage. This will be a good starting point to
begin writing tests for AHS. Tx,

[~vinodkv], I recall one problem. WRT the test, if it has reference to RM, I think it's good
to be placed either in resourcemanager or server-test sub-project, instead of applicationhistoryservice
sub-project. This is because resourcemanager sub-project will eventually refer applicationhistoryservice.
Then, if applicationhistoryservice already has the dependency on resourcemanager, there will
be cyclic dependency. Recall the issue in YARN-641.
