Apache mesos interview questions

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.

#1 What is scheduler in framework?

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.

#2 Explain Apache Spark?

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.

#3 What are the differences between Mesos and YARN?

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.
