that is, everything that is global, extended with anything that is at the component level. If a component overrides the global value, that override is picked up It's essentially a form of prototype-based programming, except only of properties, not methods: http://en.wikipedia.org/wiki/Prototype-based_programming On 11 November 2014 01:30, hsy...@gmail.com <hsy...@gmail.com> wrote: > Thanks Ted, but back to my first question, how can you define component > level property? in appConfig.json? > > I tried to define like this : > > > { > "schema": "http://example.org/specification/v2.0.0";, > "metadata": { > }, > "global": { > "application.def": "app-package-0.1.zip", > "java_home": "/usr/lib/jvm/java-7-oracle/", > "package_list": "files/app.tgz", > "agent.conf": "/user/siyuan/agent/conf/agent.ini", > > "site.global.app_user": "siyuan", > "site.global.app_root": > "${AGENT_WORK_ROOT}/app/install/kafka_2.10-0.8.1.1", > "site.global.app_install_dir": "${AGENT_WORK_ROOT}/app/install", > "site.global.pid_file": "${AGENT_WORK_ROOT}/app/run/app.pid", > > }, > "components": { > "COMPONENT1": { > *"mykey": "myvalue"* > }, > "slider-appmaster": { > "jvm.heapsize": "256M" > } > } > } > > Is it able to make the component1 read the value for *mykey* ？ > > > Best, > Siyuan > > On Mon, Nov 10, 2014 at 4:15 PM, Ted Yu <yuzhih...@gmail.com> wrote: > > > To my knowledge, there is no direct support for this. > > > > You can create different components, each with corresponding properties. > > > > Cheers > > > > On Mon, Nov 10, 2014 at 4:13 PM, hsy...@gmail.com <hsy...@gmail.com> > > wrote: > > > > > If I want to have several instances of some component.
