Apache Mesos Essentials

By: Dharmesh Kakadia

Overview of this book

<p>Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. It allows developers to concurrently run the likes of Hadoop, Spark, Storm, and other applications on a dynamically shared pool of nodes. With Mesos, you have the power to manage a wide range of resources in a multi-tenant environment.</p> <p>Starting with the basics, this book will give you an insight into all the features that Mesos has to offer. You will first learn how to set up Mesos in various environments from data centers to the cloud. You will then learn how to implement self-managed Platform as a Service environment with Mesos using various service schedulers, such as Chronos, Aurora, and Marathon. You will then delve into the depths of Mesos fundamentals and learn how to build distributed applications using Mesos primitives.</p> <p>Finally, you will round things off by covering the operational aspects of Mesos including logging, monitoring, high availability, and recovery.</p>

Advanced configuration for Hadoop on Mesos


Hadoop has many parameters that affect its performance and fault tolerance behavior. You may want to tune the following options suitable for your cluster and workload.

Task resource allocation

This is used to control the amount of resources allocated to Hadoop tasks. By setting the following parameters in conf/core-site.xml, Mesos will be instructed to assign an appropriate CPU, memory (in MB), and diskspace (in MB) resources.

Note

Note that the memory includes the JVM overhead (~10%).

<property>     
    <name>mapred.mesos.slot.cpus</name>     
    <value>1</value> 
</property>   
<property>     
    <name>mapred.mesos.slot.mem</name>     
    <value>1024</value>
</property> 
<property>     
    <name>mapred.mesos.slot.disk</name>     
    <value>1024</value> 
</property>  

The following parameters control the resource policies of Mesos:
