Apache mesos interview questions

Apache Mesos is an open source type of software. Apache Mesos is a cluster manager that handles the workloads of the distributed environment through dynamic resource sharing and isolation. The reputed companies like Twitter, Airbnb and Xogito uses the Apache Mesos.

Aurora is a type of service scheduler that has the ability to run on the top of Mesos. It will help to enable the long-running services that takes advantages of Mesos.

Marathon is a type of private pass that is built on Mesos. It will automatically handle all the hardware and the software parts and also assure that the app is on.

The following are the main components of the Apache Mesos:

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

The following are the data processing in Apache Mesos:

• Cray Chappel
• Depark
• Exelixi
• Hadoop
• Hama

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

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.

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 other projects of the Apache:

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

The Apache Mesos mostly runs on Linux and Mac OSX.

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 main components of the framework:

1. Scheduler
2. Executor

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.

A mesosphere is a type of software solution 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 following are the main differences between Apache Mesos and Apache Spark:

• Apache Spark supports the authentication along with the shared secrets with the entire cluster manages. The Apache Mesos provides the authentication for any of the entity interacting of the cluster.
• Apache Spark has the Web UI to monitor the application whereas Apache Mesos provides all the numerous means for the master and slave nodes accessible along with the URL.

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.
