Hadoop Operational Modes

Local (Standalone) operation
- All Hadoop deamons (NameNode, DataNode, JobTracker, Task Tracker) are running on a single Java process (JVM)
- Uses local file system for storage
Pseudo-distributed operation (test & development)
- Each Hadoop daemon runs in a separate Java process (JVM) but physically on a single machine
Fully-distributed operation (production)
- Each Hadoop daemon runs on a different machine
- The power of Hadoop – parallel processing, scalability, automatic replication management, fault-tolerance, data consistency, workflow management – gets realized only in this mode

Thank you for the thorough coverage of Hadoop and the Cloudera services. The topic is huge with all the different services it offers. Thank you..

John Sylora

Excellent detailed presentations on the vast array of technologies which make up the Hadoop ecosystem. Course was well presented with a balanced mixture of presentations and labs. I will be recommending the company I work for use JPassion for their training. I would thoroughly recommend JPassion courses to anyone who wishes to keep themselves uptodate. Thanks to Sang Shin for his great work - he has definately demonstrated his passion for technology in his delivery of this code camp!

Thank you for the great codecamp. This stimulated me to learn about Hadoop. You reviewed so many topics, it was great to get this overview. They all have unusual names and today you reviewed HBase, sqoop, oozie, and flume. Thanks for taking the time to put all this material together then review it live with us.
