Subject [jira] [Updated] (YARN-4061) [Fault tolerance] Fault tolerant writer for timeline v2
Date Thu, 20 Aug 2015 00:24:45 GMT

    Attachment: FaulttolerantwriterforTimelinev2.pdf

I put some thoughts on this issue and got some suggestions from [~vinodkv]. This is the design
doc of this writer. Any comments and suggestions are more than welcome. 

Right now one issue we'd like to decide is, shall we start with a pure file system based logger,
or an HDFS based logger? I incline to the latter but would like to hear more comments. Thanks!
