[EAGLE-556] Install/Update Alert Topology Metadata when start alert engine Currently alert engine requires additional metadata like TopologyMeta, which in fact could be automatically generated during starting alert engine. *Changes* * Add "ApplicationListener" in ApplicationProvider to support extensible application lifecycle management callback listener * Implement AlertUnitTopologyAppListener to add topology metadata when topology is running and remove topology metadata when topology is stopped You can merge this pull request into a Git repository by running: $ git pull https://github.com/haoch/incubator-eagle EAGLE-556 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/incubator-eagle/pull/493.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #493 ---- commit aa88bea11a4b7cb0b488c4b4defcac5b7a27aee4 Author: Hao Chen <h...@apache.org> Date: 2016-10-11T08:46:25Z Add application listener commit bce38f0c8625761b7c1d33bea4a3ec0c203694c2 Author: Hao Chen <h...@apache.org> Date: 2016-10-11T08:47:21Z Fix conflict on executable flag commit 6c2dae7744baf7796fa9c01119cd132a6c986b6f Author: Hao Chen <h...@apache.org> Date: 2016-10-11T09:37:39Z Integrate ApplicationListener with ApplicationManagementService commit 84bff0330c6a8371d57f9737f3564c6c274bc090 Author: Hao Chen <h...@apache.org> Date: 2016-10-11T15:41:21Z Add application listener framework and support setup topology metadata * Add topology metadata when topology is running * Remove topology metadata when topology is stopped ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
