Subject [Incubator Wiki] Update of "HoyaProposal" by SteveLoughran
Date Wed, 15 Jan 2014 17:26:56 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "HoyaProposal" page has been changed by SteveLoughran:

   1. Tie in better with HBase, Accumulo and other projects that can take advantage of a YARN
cluster -yet which are not ready to be explicitly migrated to YARN.
   1. Build a system that can be used to migrate more distributed applications into YARN clusters.
+ == Longer Term Options ==
+ There are some longer term possibilities that could improve Hoya
+  1. A web UI tracking and redirecting to the (changing) location of deployed services.
+  1. Adding metrics for management tools.
+  1. Explore/Research sophisticated placement and failure tracking algorithms. Its precisely
because this is a less mature product that we can experiment here.
+  1. Explore load-driven cluster sizing.
+ Hoya is already driving some Hadoop development, such as [[|YARN-896]].
It's also a place where we can evolve features
+ and get practical experience using them before submitting them to the Hadoop codebase.
+ We may also benefit from changes made to HBase and Accumulo -such as assignment retention
over restart [[|HBASE-10333]]. In exchange,
these projects will get extra test suites to explore failure handling and load handling during
dynamic cluster operations -as well as the ability to host multiple instances in a single
+ YARN cluster.
  == Current Status ==
  Hoya is a very young project, six months old, and not yet in production use.
