kandi X-RAY | marathon Summary

marathon is a Scala library. marathon has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Support for DC/OS ends on October 31, 2021. We will continue to provide support for our current DC/OS customers per their contracts, of course. However, we will no longer be investing in new features or capabilities or maintaining the related repositories. If a customer wishes to continue use of the DC/OS Enterprise platform or other non-free DC/OS components, the customer can purchase an End-of-Life License or Perpetual Use License, however support is not included in these licenses and continued use of DC/OS will be at your own discretion and risk. We apologize for any inconvenience this may have caused. We want to thank all of our loyal customers, particularly those DC/OS users who were fellow pioneers in the growth of the cloud native landscape from the beginning. Marathon is a production-proven Apache Mesos framework for container orchestration. DC/OS is the easiest way to start using Marathon. Issues are tracked in JIRA. Marathon provides a REST API for starting, stopping, and scaling applications. Marathon is written in Scala and can run in highly-available mode by running multiple copies. The state of running tasks gets stored in the Mesos state abstraction. Marathon is also used as a meta framework: you can start other Mesos frameworks such as Chronos or Storm with it to ensure they survive machine failures. It can launch anything that can be launched in a standard shell. In fact, you can even start other Marathon instances via Marathon.

You can create a function that takes in the target class name. With the class name you can query the document for all nodes that match, and change the node.style.display attribute.

QUESTION

Calculate frequencies over deciles

Asked 2021-Jun-10 at 18:03

Let's say I have SQL Server tables detailing marathon races, all of them alike. Each row is a participant and one of the columns is the finish time, [dbo].[marathon_X].[finish]. Let's assume [finish] is counted in minutes (int) for simplicity.

I'm stuck and could use help figuring out a query that divides the finish times for a certain race into deciles and counts the number of participants finishing within each decile. This so I can get an idea of the frequency distribution over different time segments (which, in this case, I expect to be something other than even, or normal for that matter).

So for example if the winner in a certain race finishes after 130 min and the last participant after 520 minutes, then in that particular race each finish time decile would be (MAX(finish) - MIN(finish))/10 = 39 min wide. And then 1st decile would be finish times within 130-168 min, 2nd would be 169-207 min, etc. I then need a count of the number of runners in each decile, the range of which will vary from race to race.

Probably stupidly simple but I haven't figured out how to NTILE this (or equivalent).

Not sure if you were looking to aggregate the final results, but that would be a small matter in the final select.

The cte will create the desired ranges. Then it becomes a small matter of joining the two sets of data.

Marathon JAVA Driver - Error when running inside an exported JAR file from Eclipse

I have got Marathon JAVA Driver to work in Eclipse and it works fine when I run the code from eclipse. However, When I export the project as runnable JAR file, and then execute the JAR file, I get the below error and the application is not launched.

ANSWER

Answered 2021-May-10 at 07:10

Marathon Java driver uses its jar files so that it can set JAVA_TOOL_OPTIONS. So it needs the jar file to be assessable in the file system.

Please check the JavaProfile.java line number 204 for reference.

For a quick fix export marathon jars and add them to class path and write a batch script to execute the test case.

Select option from Combobox using visible text

Asked 2021-Apr-08 at 07:22

I'm working with Marathon Java Driver for automating a JavaFX application. I have to select an value from a combobox based on visible text. Currently, I get all the options using .::all-options and looping through each item to get the text and compare it with the required text option. However, the time taken is high based on the number of options.

Is there any other way to select the value from combobox using visible text - something like driver.findElement(By.csslocator("combox1::value"));?

ANSWER

Answered 2021-Mar-25 at 17:02

You'll need to use a "real" downing provider like Split Brain Resolver. This lets the cluster safely down nodes that are unreachable. (As opposed to the auto downing, which downs them without consideration of it is safe or not.)

There's a separate question of why DC/OS is killing the nodes so quickly they don't get the chance to properly shut down. But I don't know DC/OS well enough to say why that could be. And, regardless, a downing provider is essential for clustered environments so you will want to get that in place anyway.

Edited due to your comments about SBR:

First I want to be clear, the marathan-api is almost certainly irrelevant here. marathon-api is how nodes discover other nodes in DC/OS. The problems you are having are with fundamental cluster problems, namely unreachable nodes. A cluster with unreachable nodes is going to act the same way, regardless of where it is running and how the nodes are discovered.
Fundamentally my best guess is that you are having problems getting clean shutdowns. If SBR is downing your entire cluster it's because it is getting to a point where there are more unreachable nodes than live clusters.

As an example, what might be happening:

You have 4 live nodes and want to upgrade.
DC/OS kills the first node. For some unknown reason you aren't getting a clean shutdown so the node is marked as unreachable. (Essentially the cluster, because it wasn't a clean shutdown doesn't node if the node still exists but is unresponsive and/or behind a partition.) There are 3 live nodes and one unreachable.
DC/OS starts the second node. Perhaps it takes a while to boot your application. So you have 3 live nodes, one unreachable node, and 1 unready node.
DC/OS kills another node. So you have 2 live nodes, 2 unreachable nodes, and 1 unready node. At this point SBR can no longer guarantee that you haven't had a network partition because you don't have majority. At this point, in order to prevent corruption, it must stop the cluster.

So, I would recommend the following:

I don't know the details of DC/OS well enough but you probably need to slow down your rolling upgrades. In K8S I'd use something like MinReadySeconds.
You may want to consider a fifth node. Odd numbers are better because it makes majority easier to determine.
If you continue to have problems you'll need to provide more logs from the SBR decision.

SBR is the answer here. I realize that you aren't having real network partitions, but the fact that you are having unreachable nodes means that the Akka Cluster is unable to tell if there are network partitions or not and that's the root cause of the problem.

Install marathon

The by far easiest way to get Marathon running is to use DC/OS. Marathon is pre-bundled into DC/OS. Marathon requires libmesos, a shared object library, that contains JNI bindings for Marathon to talk to the Mesos master. libmesos comes as part of the Apache Mesos installation. There are three options for installing Apache Mesos. Instructions on how to install prepackaged releases of Mesos are available in the Marathon docs.
Version tags from the Mesos repository. Use ./mvm.sh --tags in order to obtain a list of available tags.
Commit hashes from the Mesos repository.
The --latest flag, which automatically chooses the latest development version: ./mvm.sh --latest.
To build Marathon from source, check out this repo and use sbt to build a universal: git clone https://github.com/mesosphere/marathon.git cd marathon sbt 'run --master localhost:5050 --zk zk://localhost:2181/marathon' Troubleshooting Failure in retrieval of IP address of the local machine will result in an error and may look like this: Failed to obtain the IP address for '<local-machine>'; the DNS service may not be able to resolve it: nodename nor servname provided, or not known Make sure that LIBPROCESS_IP environment variable is set. export LIBPROCESS_IP="127.0.0.1" When the MESOS_NATIVE_JAVA_LIBRARY environment variable is not set, the following error may occur, java.lang.UnsatisfiedLinkError: no mesos in java.library.path... Make sure that MESOS_NATIVE_JAVA_LIBRARY environment variable is set. export MESOS_NATIVE_JAVA_LIBRARY="/path/to/mesos/lib/libmesos.dylib"
Run sbt universal:packageZipTarball to package Marathon as an txz file containing bin/marathon fully packaged.
Run cd tools/packager; make tag-docker for a local Marathon docker image.
