Apache Mesos is a type of open source software that is used to manage the computer clusters. This type of software has been developed by the University of California, Berkeley. Its main motto is to distribute potent resources isolation and sharing across the distributed frameworks or the applications. The companies who use the Apache Mesos are Twitter, Airbnb, Media crossing, Xogito and Categorize. There are some of the Apache Mesos interview questions and answers that will help you a lot in gaining more knowledge about it.

Apache Mesos software has been built on the same principle on which the Linux Kernel has been built. Nowadays, Apache Mesos has been adopted by numerous companies. One of the most famous companies who use these types of software is Apple. Apache Mesos also provide faster application performance. The below are some of the Apache Mesos interview questions and answer.

The Apache Mesos mostly runs on Linux and Mac OSX.

The scheduler registers along the masters and receives all the resource offerings from the masters. The schedulers' main task is to decide what to do with resources offered by the Mesos master within the framework.

The following are the languages been supported by Apache Mesos:

  • Scala
  • Java
  • Python
  • R

Among the above languages the Scala and Phyton are mostly used.

The following are the main components of the framework:

  1. Scheduler
  2. Executor

The following are the data processing in Apache Mesos:

  • Cray Chappel
  • Depark
  • Exelixi
  • Hadoop
  • Hama

The following are the difference between Mesos and YARN:

  • Mesos has the specification to manage all the resources that are present in the data centre whereas, YARN can carefully manage the Hadoop job but they cannot manage the entire data centre.
  • Mesos are written in C++ whereas the YARN is written in Java language.
  • Mesos uses the Linux Container group but YARN uses the simple UNIX processes.
  • In Mesos, you are needed to deal with the security whereas, YARN inherits Hadoop security.
  • Mesos have a lower level of abstraction but the YARN can run on Mesos also.

Zookeeper is a type of the fundamental components of DC and OS. It depends on both the Apache Mesos and Marathon.

The framework provides an application with the API that is used to monitor the state of the tasks that the application is responsible for. Frameworks have the ability to decide that which resources they would accept and which is the appropriable computation to run on them.

The following are the other projects of the Apache:

  • Apache Mesos
  • Apache Kafka
  • Apache spak
  • Apache Handoop
  • Apache Cassandra
  • Apache Http server
  • Apache Flink

A mesosphere is a type of software solutions that expand upon the capabilities of the Apache Mesos. As a result, the Apache Mesos along with the other additional components provide new and different ways to manage the server infrastructure.

The executor is launched on the slave nodes and runs all the framework’s tasks.

The following are the modern workloads and framework that can run on the Apache Mesos:

  • Hadoop
  • Memcached
  • Ruby on Rails
  • Storm
  • JBose data
  • Grid
  • MPI
  • Spark
  • Node

The following are the long running services of the Apache Mesos:

  • Aurora runs on top of Mesos
  • Marathon which is a private pass that is built on Mesos
  • Singularity is a type of scheduler that is used for running the Mesos tasks.
  • SSP is a type of single web application that is used to provide a white label Megaupload. It is used for storing and sharing of files.

Apache Spark is a type of lightning fast cluster computing technology that is designed for fast computation. The Apache Spark is mainly based on the Hadoop MapReduce.

The following are the main components of the Apache Mesos:

  • Zookeeper
  • Mesos Masters
  • Mesos Slaves
  • Frameworks
  • Chorons, Marathon
  • Aurora
  • Hadoop
  • Jekins
  • Spark
  • Torque
