Subject Re: [VOTE] Release Apache Hadoop 2.4.0
Date Mon, 31 Mar 2014 18:23:45 GMT
Hi Sandy,

Application History Server (we prefer to call it Timeline Server instead
now) is going to be shipped in 2.4 without security. I've already wrote a
document about what it is, what's the current status, and how to config and
start it. Via the document, hopefully the users are clear about the
timeline server. There's another jira, YARN-1876, in which I've attached a
patch about the REST APIs of using generic history data and per-framework
data. However, it seems to be to late to get it in.

For the timeline store, we have already one implementation based on
Leveldb. We have monitored its performance closely and reviewed its
license, and believed it should be a good shape now. Currently the timeline
store is for storing per-framework data only, while we eventually hope to
move the generic data there as well.

Thanks,
Zhijie
