Hadoop Administrator Training

This four-day course provides practical and theoretical knowledge necessary to operate a Hadoop cluster. We put high emphasis on practical hands-on exercises that aim to prepare participants to work as effective Hadoop administrators.

During the training, you will act as a Hadoop administrator who is given 7 machines in the public cloud. Your goal is to install and properly configure a multi-node Hadoop cluster with popular components from the Hadoop Ecosystem (e.g. Spark, Hive, Oozie, Sqoop). Your cluster must be fully-functional and able to survive various failures. You will change various configuration settings, deploy HA for HDFS and YARN, tweak the YARN scheduler, analyze values of various Hadoop-related metrics, define and respond to alerts and perform popular maintenance tasks (e.g. adding new nodes, balancing HDFS, troubleshooting failed applications).

The next Hadoop Administration Training  will take place in Warsaw from 24th of April until 27th of April 2017. The cost of the training is 5500 PLN per person+tax. The workshop will be conducted in Polish. Before you register please read carefully the Term&Conditions of our trainings.


Basic experience with any Linux system. No prior knowledge about Hadoop is required.

Target Audience

IT professionals who will be responsible for installing, configuring and managing Hadoop clusters.

Possible Customization

Thanks to having practical experience with Cloudera or Hortonworks distributions, we can offer flexible training course where the agenda can be customized to fit your production cluster. Possible customization is available:

  • HDP (Apache Ambari) or CDH (Cloudera Manager)
  • Addition of some of components: Cloudera Impala, Apache Tez, Facebook Presto, Apache Flume, Apache Kafka, Apache Sentry, Apache Ranger, Search (Apache Solr)
  • Exercises for the Capacity Scheduler or the Fair Scheduler
