[Blueprint servercloud-q-bigdata-hadoop] Next steps for Hadoop on Ubuntu

[James Page]

Blueprint changed by James Page:

Whiteboard changed:
  UDS Discussion Topics:
  
  Quick 101 on current packaging and general approach.
   - Based on binary distributions from upstream
   - Re-use of Bigtop packaging where appropriate
   - Rebuild of native components (to support 12.04 and ARM).
  Alignment to next release of Apache Bigtop and potential collaboration (Ubuntu 12.04 will be the targetted release for Bigtop 0.4.0).
   - Stick with Hadoop 1.x or move to 2.x (former 0.23) branch (or both).
   - Process and technology for feeding back patches to Bigtop (not easy ATM).
   - Work to support Ubuntu 12.04 as target version for Bigtop.
  Updates to stable packages for Ubuntu 12.04
   - Release/Testing process
  OpenJDK7 as default Java in 12.10 - support from upstreams and testing process
  Revisit packaging from source.
  Testing of packages and functionality
  Enable kerberos authentication in the current charmset?
  Use of puppet modules in juju charms.

  User Stories:
  
- TBC
+ Toby want todo some testing of hadoop-2.0 prior to upgrading his
+ existing hadoop-1.0.x deployments. He is easily able to deploy a
+ hadoop-2.0 cluster using Juju and the hadoop charm from the Juju Charm
+ Store.
+ 
+ Frank likes the idea of using Juju to deploy hadoop but he's unsure
+ about the quality of the charms.  He can easily see the depth of testing
+ being undertaken on each of the charms and decides that this is the
+ right choice for his deployment.
+ 
+ Janice wants to deploy a secure hadoop cluster.  She is able to leverage
+ the hadoop charms inconjunction with kerberos to support this
+ requirement.
  
  Assumptions:
  
- TBC
+ - hadoop-2.0 will be packaged alongside hadoop-1.0.x (different PPA or different pkg names).
+ - Hadoop will run OK on openjdk-7
+ - Suitable resources for regular testing of hadoop charms.
+ - Changes can be fed back to bigtop easily
+ - 
  
  Test Plans:
  
  TBC
  
  Release Note:
  
- TBC
+ N/A - still outside of the main archive.
