harisekhon/hadoop repository overview

⁠Apache Hadoop

https://hadoop.apache.org/⁠

Big Data Distributed Storage and Compute Software

• Yarn - Distributed Processing Framework for running MapReduce, Spark and other application frameworks
• HDFS - Distributed Storage

By default starts a pseudo-distributed cluster of 4 daemons in a single container:

• Yarn
  • ResourceManager - Cluster Processing Master (submit jobs here)
  • NodeManager - Cluster Processing Worker
• HDFS
  • NameNode - Filesystem Master
  • DataNode - Filesystem Worker

Perfect for development and testing. Recommended to use Docker with 4GB+ RAM for this pseudo-cluster container.

For real scaling just start a single daemon in each container for fully distributed setup.

To run the all-in-one-container cluster and expose all the UIs for NodeManager, ResourceManager, NameNode and DataNode respectively, do:

docker run -ti -p 8042 -p 8088 -p 19888 -p 50070 -p 50075 harisekhon/hadoop

or with docker-compose:

docker-compose up

or without docker-compose, a shortcut for the docker run command:

make run
