            Intellij Idea Code Coverage Vs Maven Jacoco
            Asked 2021-Mar-10 at 21:45

            when I run my tests in Intellij idea choosing code coverage tool as JaCoCo and include my packages I see I get 80% above coverage in the report but when I run it using maven command line I get 0% in JaCoCo report below are two questions.

            1. can I see what command Intellij Idea Ultimate version is using to run my unit tests with code coverage ?

            2. Why my maven command mvn clean test jacoco:report is showing my coverage percentage as 0%.

            This is a Scala maven project.

            My POM.xml file:-



            Answered 2021-Feb-03 at 22:16

            Assuming that you are using JaCoCo with cobertura coverage you need to declare the dependencies and the plugin to run the command mvn cobertura:cobertura.



            What is the difference between Driver and Application manager in spark
            Asked 2020-Sep-16 at 16:22

            I couldn't figure out what is the difference between Spark driver and application master. Basically the responsibilities in running an application, who does what?

            In client mode, client machine has the driver and app master runs in one of the cluster nodes. In cluster mode, client doesn't have any, driver and app master runs in same node (one of the cluster nodes).

            What exactly are the operations that driver do and app master do?




            Answered 2020-Sep-16 at 10:59

            As per the spark documentation

            Spark Driver :

            The Driver(aka driver program) is responsible for converting a user application to smaller execution units called tasks and then schedules them to run with a cluster manager on executors. The driver is also responsible for executing the Spark application and returning the status/results to the user.

            Spark Driver contains various components – DAGScheduler, TaskScheduler, BackendScheduler and BlockManager. They are responsible for the translation of user code into actual Spark jobs executed on the cluster.

            Where in Application Master is

            The Application Master is responsible for the execution of a single application. It asks for containers from the Resource Scheduler (Resource Manager) and executes specific programs on the obtained containers. Application Master is just a broker that negotiates resources with the Resource Manager and then after getting some container it make sure to launch tasks(which are picked from scheduler queue) on containers.

            In a nutshell Driver program will translate your custom logic into stages, job and task.. and your application master will make sure to get enough resources from RM And also make sure to check the status of your tasks running in a container.

            as it is already said in your provided references the only different between client and cluster mode is

            In client, mode driver will run on the machine where we have executed/run spark application/job and AM runs in one of the cluster nodes.


            In cluster mode driver run inside application master, it means the application has much more responsibility.

            Invalid class exception in apache spark

            I am trying to run a spark job using spark-submit. When I run it in eclipse the job runs without any issue. When I copy the same jar file to a remote machine and run the job there I get the below issue



            Answered 2017-Aug-11 at 12:27

            I finally resolved the issue. I commented out all the dependencies and uncommented them one at a time. First I uncommented spark_core dependency and the issue got resolved. I uncommented another dependency in my project which again brought back the issue. Then on investigation I found that the second dependency was in turn having dependency of a different version(2.10) of spark_core which was causing the issue. I added exclusion to the dependency as below:

            Answered 2018-Nov-03 at 02:56

            Can I get more details about how you are running the spark job? If you are using custom distribution such as Cloudera or Horton works, you may have to use their libraries to compile and spark-submit will use the distribution installed classpath to submit the job to cluster.

            To get started, please add % provided to the library in sbt file so that it will use the particular library from the classpath of spark installation.



            Spark ClassCastException cannot assign instance of FiniteDuration to field RpcTimeout.duration
            Asked 2018-Jun-25 at 02:14

            What is this? Wrong library at classpath? What to try?



            Answered 2018-Feb-20 at 08:41

            Scala classes are packed to spark application distributive which causes wrong version of the class in the classpath.

            The fix would be to change the scope of all conflicting dependencies to provided.

            Answered 2018-Mar-25 at 22:38

            I think I had two main issues.

            1. Spark is not compatible with scala 2.12 yet. So moving to 2.11.12 solved one issue
            2. The second issue is that for intelliJ SBT console to reload the build.sbt you either need to kill and restart the console or use the reload command which I didnt know so I was not actually using the latest build.sbt file.
