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. http://pad.ubuntu.com/uds-q-servercloud-q-bigdata-hadoop 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.
