Subject [jira] [Commented] (YARN-3049) [Storage Implementation] Implement storage reader interface to fetch raw data from HBase backend
Date Mon, 03 Aug 2015 22:50:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-3049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14652709#comment-14652709

Sangjin Lee commented on YARN-3049:
-----------------------------------

I like that approach better than the previous. Thanks for the update.

How would we be able to handle the "app finished" event? That needs to be supported too for
other tables, and adding another flag to the context doesn't seem too appealing? Also, the
timestamp of these events are important as they need to be written to some secondary tables.
How can we captured them? If {{HBaseTimelineWriterImpl}} needs to recognize and read the event
timestamp, then we might as well just look for those events, right? Any thoughts on these?
