Subject [jira] [Commented] (YARN-3411) [Storage implementation] explore the native HBase write schema for storage
Date Mon, 27 Apr 2015 17:58:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-3411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14514554#comment-14514554

Vinod Kumar Vavilapalli commented on YARN-3411:
-----------------------------------------------

There is no single YARN artifact. hbase-client may depend on yarn-client. But yarn-timeline-service
may depend on hbase-client. There is no cause for concern. yarn-timeline-service should depend
on the last stable hbase-client that we will test with and support.

> 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.
