Subject [jira] [Commented] (YARN-1635) Implement a Leveldb based ApplicationTimelineStore
Date Wed, 05 Feb 2014 05:04:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-1635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13891805#comment-13891805
] 

Billie Rinaldi commented on YARN-1635:
--------------------------------------

I have a new patch ready addressing most of the comments, but haven't attached it yet.  This
patch applies on top of YARN-1636.  I've added more comments to GenericObjectMapper but haven't
renamed it yet.  The name comes from ObjectMapper, since it does ObjectMapper-like things
without making you specify the class to deserialize into.  I could see renaming it to ATSUtil
or LeveldbApplicationTimelineStoreUtil.  Let me know what you think after seeing the additional
comments.

with and for small deployments.
