[Review Queue] Tez and Shoutcast

[Whit Morriss]

Today I reviewed a bundle and a charm, both from our esteemed Chuck Butler.

The tez bundle sets up a framework for doing realtime high volume data
processing using Yarn and hadoop:

Shoutcast is the venerable internet radio server:

Both worked great and got +1s from me.  I did run into a couple juju
related bumps working on ec2.  First was forgetting to set my instance-type
constraint and getting dinged for limited capacity on m1.smalls:

    agent-state-info: 'cannot run instances: We currently do not have
sufficient m1.small
      capacity in the Availability Zone you requested (us-east-1d). Our
system will
      be working on provisioning additional capacity. You can currently get
m1.small
      capacity by not specifying an Availability Zone in your request or
choosing
      us-east-1c, us-east-1a. (InsufficientInstanceCapacity)'

The second was an error that popped up several times.  These machine hung
around in status, but blocked deploy until destroyed.  Destroying service
and machine cleared up the issue and allowed deployment.

    agent-state-info: 'cannot run instances: No default subnet for
availability zone:
      ''us-east-1e''. (InvalidInput)'
