Subject [jira] [Commented] (DRILL-1170) YARN support for Drill
Date Tue, 02 May 2017 15:03:04 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993036#comment-15993036

Paul Rogers commented on DRILL-1170:
------------------------------------

Our original intent was to contribute DoY to the Apache Drill project. However, it is ~12K
lines of code, which was too much for the project committers to review. So, we postponed the
contribution until we could find someone sufficiently motivated to do a code review. Of course,
the task of the reviewer should be simpler now; DoY has been in use for about 9+ months so
there should not be too many obvious bugs to find...

That said, if you can act as a first-line code reviewer, I can restart the submission process
so that DoY becomes part of Apache Drill.

> This is a tracking item to make Drill work with YARN.
> Below are few requirements/needs to consider.
> - Drill should run as an YARN based application, side by side with other YARN enabled
applications (on same nodes or different nodes). Both memory and CPU resources of Drill should
be controlled in this mechanism.
> - As an YARN enabled application, Drill resource consumption should be adaptive to the
load on the cluster. For ex: When there is no load on the Drill , Drill should consume no
resources on the cluster.  As the load on Drill increases, resources permitting, usage should
grow proportionally.
> - Low latency is a key requirement for Apache Drill along with support for multiple users
(concurrency in 100s-1000s). This should be supported when run as YARN application as well.
