Apache Hadoop YARN (Yet Another Resource Negotiator) is a cluster management technology. It decouples MapReduce’s resource management and scheduling capabilities from the data processing component, enabling Hadoop to support more varied processing approaches and a broader array of applications. YARN, (or sometimes called as MR2), is an extended and an improved version of MR1. It was… Continue reading Term of the Week : YARN

Fair Scheduler is a pluggable scheduler for Hadoop that allows YARN applications to share resources in large clusters fairly. As the name suggests, it allocates resources such that all applications get an equal share. By default, this is done on the basis of the memory. But, i t can be configured to schedule with both memory… Continue reading What is a Fair Scheduler in Hadoop?

Capacity Scheduler is a pluggable scheduler for Hadoop which allows for multiple-tenants to securely share a large cluster such that their applications are allocated resources in a timely manner under constraints of allocated capacities. Before the onset of Big Data and Hadoop, every organization had their own set of resources that had sufficient capacity to meet the… Continue reading What is a Capacity Scheduler in Hadoop?
Apache Sqoop is a tool designed for transferring bulk data between Apache Hadoop and relational databases. It supports incremental loads of a single table or a free form SQL query as well as saved jobs which can be run multiple times to import updates made to a database since the last import. Imports can also be… Continue reading What is Apache Sqoop?
