问题 How can I run spark in headless mode? Currently, I am executing spark on a HDP 2.6.4 (i.e. 2.2 is installed by default) on the cluster. I have downloaded a spark 2.4.1 Scala 2.11 release in headless mode (i.e. no hadoop jars are built in) from https://spark.apache.org/downloads.html. The exact name is: pre-built with scala 2.11 and user provided hadoop Now when trying to run I follow: https://spark.apache.org/docs/latest/hadoop-provided.html export SPARK_DIST_CLASSPATH=$(hadoop classpath)

问题 According to Spring Boot documentation, properties can be grouped and a property may appear in more than one group. But at the moment when we create a property class marked with @ConfigurationProperties(prefix="test1") the group name will be the prefix which is test1. Now if I have another property class for example with prefix as "test2" how can I say this latter one has a property from the group test1? --- UPDATE --- Added nested class but it's not working @Configuration @Profile({"wmx"})

问题 I had set up my git to use P4Merge as the diff tool, as described here. So, git diff will trigger the P4Merge. However, sometimes I find working with the UNIX diff is faster and more efficient (because no GUI involved). How do I set up git so that I can easily choose which diff tool I would like to trigger? Is this possible? For example: $ git diff # to trigger P4Merge $ git difftool # to trigger UNIX diff My git config --list : code.editor=vi merge.tool=p4merge mergetool.extMerge.cmd

问题 I was curious how the following line works for configuring log4net in an assembly: [assembly: log4net.Config.XmlConfigurator(Watch=true)] I'm guessing this gets called sometime before the runtime invokes "main()" but when does this occur, and what are the implications? Are there other frameworks/libraries that use this assembly attribute for loading an initial context like this? Are there any advantages/disadvantages for doing something like this, as opposed to calling a "Configure" method in

问题 This question already has answers here : How to portably read configuration data from a servlet (4 answers) Closed 5 years ago . I run webapp on Jetty.

E.g. final String loc = System.getProperty(FACTORY); Now I can start jetty with D switch to provide $FACTORY on the command line but I rather put it in
