Apache Hadoop: YARN Overview | Big Data Hadoop Tutorial

This lecture is all about Hadoop resource management component i.e. YARN (Yet Another Resource Negotiator) where we have discussed what is Hadoop YARN, significance of YARN, architecture of YARN and the process flow.

In the previous lecture we have seen Querying Cassandra, Hive using Presto where we have set the configuration properties file to connect presto to our underlying Cassandra cluster and submitted SQL queries on top of our existing Cassandra keyspace. Below are commands for this lecture:

scl enable python27 bash

service cassandra start

nodetool enablethrift

cqlsh

vi cassandra.properties
--------------------------------------
connector.name=cassandra
cassandra.contact-points=127.0.0.1
--------------------------------------
bin/launcher start

bin/presto --server 127.0.0.1:8090 --catalog hive,cassandra
