How to specify system property in hadoop except modify hadoop-env.sh?

若如初见. 提交于 2019-12-05 06:55:27
问题 I'd like to set system property (not hadoop property) when running hadoop jobs. I found that it's not easy to setting system property. Even I set the property in shell export HADOOP_OPTS="$HADOOP_OPTS:-Dproperty=value" It's still not working. The "-D" option of hadoop command line is only for Configuration, not system property. So the "-D" option also not working Anyone has ideas ? thanks 回答1: Why not simply use -Dfoo.bar=example in-line when starting the job via command line, like so: hadoop

How do I set a system property for my project in sbt?

问题 I'm sure I'm missing something really simple... I want to set the system property java.awt.headless to true for my sbt project. Reading the page on properties I think that I need to use system or systemOptional . In my project file I've tried things like: lazy val javaAwtHeadless = system[Boolean]("java.awt.headless") Setting it as a user property (e.g. lazy val javaAwtHeadless = property[Boolean] ) and setting the accompanying value in build.properties made the property visible in the sbt

Recursively change system property at runtime in java

旧时模样 提交于 2019-12-04 15:34:33
I am having a question and searching for an example for changing system property at runtime in java. In other words , I am having a standalone library which will load System.setProperty("javax.net.ssl.trustStore", trustStorePath) where the value of trustStorePath will change according to condition. If condition changes then I need to change the value of trustStorePath and need to set System Property. But the story is when I set the value for very first time, it stores the value and use it even if I change the value of trustStorePath and again set system property. The change did not reflect. So

How to ignore expired certificates from outside a Java application?

问题 We have a Java application that we need to ignore an expired self-signed cert, however we cannot modify the code to do this. I wondering if there was a System Property or environment variable that we could provide at start up that would allow us to have all expired cert's ignored for now, or even be more specific and provide externally the specific cert that we would like to have the expiration ignored. Anyone have any ideas that would work? 回答1: An alternative might be to use keytool to

Set System Property for JUnit Runner (Eclipse) to test a Spring Web App

问题 Our web app uses SystemPropertyPlaceholder to load property files depending on the value of a system property (see below) The default setup for running it locally is stored in application.properties . On the production server we currently just set "env" to "production" before deploying the app and it will load production.properties . Now for testing the app a test.properties file should be used. If I run all of the tests say in our jenkins build, adding -Denv=test will work as expected. But
