问题 I was behind a proxy when I setup play framework. I edited the ~/.activator/activatorconfig.txt file and it worked fine. Now I need to remove that proxy to work on a different network. I commented out the line but the activator script still tries to use the proxy for connection, when I run ./activator new (or ./activator ui). The file currently looks like this # This are the proxy settings we use for activator # Multiple proxy hosts can be used by separating them with a '|' sign # Do not

问题 I have a sample Spark Code where I am trying to access the Values for tables from the Spark Configurations provided by spark_conf Option by using the typeSafe application.conf and Spark Conf in the Databricks UI. The code I am using is below, When I hit the Run Button in the Databricks UI, the job is finishing successfully, but the println function is printing dummyValue instead of ThisIsTableAOne,ThisIsTableBOne... I can see from the Spark UI that, the Configurations for TableNames are being

问题 I am currently working with Akka Stream Kafka to interact with kafka and I was wonderings what were the differences with Kafka Streams. I know that the Akka based approach implements the reactive specifications and handles back-pressure, functionality that kafka streams seems to be lacking. What would be the advantage of using kafka streams over akka streams kafka? 回答1: Your question is very general, so I'll give a general answer from my point of view. First, I've got two usage scenario:

问题 Using typesafe config, how do I override the reference configuration with an environment variable? For example, lets say I have the following configuration: foo: "bar" I want it to be overriden with the environment variable FOO if one exists. 回答1: If I correctly understood your question, the answer is here. You can do foo: "bar" foo: ${?FOO} 回答2: The official doc now describes it very clearly and supports multiple options for this. Here is a brief summary... Most common way is to use this

问题 This is by large combination of design and code problem. Use Case - Given many log files in range (2MB - 2GB), I need to parse each of these logs and apply some processing, generate Java POJO . - For this problem, lets assume that we have just 1 log file - Also, the idea is to making best use of System. Multiple cores are available. Alternative 1 - Open file (synchronous), read each line, generate POJO s FileActor -> read each line -> List<POJO> Pros : simple to understand Cons : Serial

问题 I need to refer to java.io.tmpdir in my application.conf file I printed content of my config with val c = ConfigFactory.load() System.err.println(c.root().render()) and it renders it like # dev/application.conf: 1 "myapp" : { # dev/application.conf: 47 "db" : { # dev/application.conf: 49 "driver" : "org.h2.Driver", # dev/application.conf: 48 "url" : "jdbc:h2:file:${java.io.tmpdir}/db;DB_CLOSE_DELAY=-1" } ... } # system properties "java" : { # system properties "io" : { # system properties

问题 I am using the typesafe config library in my code and then I generate a jar file. The application works fine when I embed the reference.conf file inside the jar. But is it possible to provide the config file as a parameter to the jar ? for example java -DmyconfigFile=/dir/dir/reference.conf -jar myjar package.class.myobject. 回答1: Yes it is. See this thread on using an external akka config here. java -Dconfig.file=/dir/dir/reference.conf -jar myjar package.class.myobject. 来源： https:/

问题 I'm trying in Scala to get a list from a config file like something.conf with TypeSafe . In something.conf I set the parameter: mylist=["AA","BB"] and in my Scala code I do: val myList = modifyConfig.getStringList("mylist") Simple configuration parameters works fine but could somebody give me an example of how to extract a list? 回答1: As @ghik notes, the Typesafe Config library is Java based, so you get a java.util.List[String] instead of a scala.List[String] . So either you make a conversion
