Subject [jira] [Commented] (YARN-3411) [Storage implementation] explore the native HBase write schema for storage
Date Thu, 21 May 2015 16:21:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-3411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14554599#comment-14554599
] 

Sangjin Lee commented on YARN-3411:
-----------------------------------

This constructor ({{HBaseTimelineWriterImpl(Configuration)}}) will not be used by non-test
code as it is instantiated via the no-arg constructor. I think we should simply remove this.
I'm fine with cleaning this up after the performance test.

> There is work that's in progress to implement the storage based on a Phoenix schema (YARN-3134).
> In parallel, we would like to explore an implementation based on a native HBase schema
for the write path. Such a schema does not exclude using Phoenix, especially for reads and
offline queries.
> Once we have basic implementations of both options, we could evaluate them in terms of
performance, scalability, usability, etc. and make a call.
