Subject [jira] [Commented] (YARN-3411) [Storage implementation] explore the native HBase write schema for storage
Date Tue, 19 May 2015 02:47:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-3411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14549692#comment-14549692
] 

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

It seems like the line that adds the hbase configuration was removed from HBaseTimelineWriterImpl.
Is that intentional? How would it be able to use and load hbase configuration then? Come to
think of it, I think we may need to add both hbase-site.xml and hbase-default.xml?

{code}
conf.addResource("hbase-default.xml");
conf.addResource("hbase-site.xml");
{code}

> 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.
