Jeff Hammerbacher commented on HADOOP-6959:
-------------------------------------------
Why should we reuse HOD for this purpose? Mesos (http://github.com/mesos/mesos)
seems like a more actively developed place to start.

> Work on a computation model for services on the grid. The model would include:
> Various tools for defining clients and servers of the service, and at the
> least a C++ and Java instantiation of the abstractions
> Logical definitions of how to partition work onto a set of servers, i.e. a
> generalized shard implementation
> A few useful abstractions like locks (exclusive and RW, fairness), leader
> election, transactions,
> Various communication models for groups of servers belonging to a service,
> such as broadcast, unicast, etc.
> Tools for assuring QoS, reliability, managing pools of servers for a service
> with spares, etc.
> Integration with HDFS for persistence, as well as access to local filesystems
> Integration with ZooKeeper so that applications can use the namespace
