Tachyon-Mesos

A Mesos Framework for Tachyon, a memory-centric distributed file system.

Word of Warning

This is the outcome of a brief hackathon, suitable only for fun and collaboration.

Prerequisites

• A Mesos cluster
• Java JDK
• SBT

Usage

$ sbt "run {tachyonUrl} {mesosMaster} {zookeeperAddress}"

Where mesosMaster is of the same form that the mesos-slave program accepts and where zookeeperAddress is of the form host:port.

Alternatively, if developing within the vagrant VM:

$ bin/run-dev

Design

Tachyon-Mesos Scheduler

The scheduler:

• registers as a framework with a Mesos master, naturally
• links against the tachyon library and starts a Tachyon Master in the same process.
• launches Tachyon worker processes on Mesos

Assumptions

• Fault tolerance for the Tachyon-Mesos scheduler can be achieved by running with a meta-framework such as Marathon
