Hadoop container, runs single node stand-alone or can be configured into a cluster. Runs HDFS and/or Yarn.

To run:

  docker run -p 9000:9000 cybermaggedon/hadoop:2.8.0

To persist data, mount a volume on /data:

  docker run -p 9000:9000 -v /data/hadoop:/data cybermaggedon/hadoop:2.8.0

To run in cluster mode, you need to change some environment variables:

• DAEMONS: Comma-separated list of daemons to start. Valid daemons are: namenode, secondarynamenode, datanode for clustered HDFS. For Yarn, resourcemanager, nodemanager and proxyserver. Default is everything except proxyserver.
• NAMENODE_URI: URI of the HDFS namenode e.g. hdfs://host1:9000, default is hdfs://localhost:9000.
• DFS_REPLICATION: Replication factor, default is 1. 3 is good if you want a data-resilient cluster, but you need at least 3 nodes.
• RESOURCEMANAGER_HOSTNAME: Hostname for nodemanagers to locate the resourcemanager.

Running an HDFS cluster:

  # Master
  docker run --rm -e DAEMONS=namenode,datanode,secondarynamenode \
      --name=hadoop01 -p 50070:50070 -p 50075:50075 -p 50090:50090 \
      -p 9000:9000 cybermaggedon/hadoop:2.8.0

  # Slaves
  docker run --rm -e DAEMONS=datanode -e NAMENODE_URI=hdfs://hadoop01:9000 \
      --name=hadoop02 --link hadoop01:hadoop01 -P cybermaggedon/hadoop:2.8.0
  docker run --rm -e DAEMONS=datanode -e NAMENODE_URI=hdfs://hadoop01:9000 \
      --name=hadoop03 --link hadoop01:hadoop01 -P cybermaggedon/hadoop:2.8.0
      

or a Yarn cluster:

  # Master
  docker run --rm -e DAEMONS=resourcemanager,nodemanager \
      -e RESOURCEMANAGER_HOSTNAME=localhost --name=hadoop01 \
      -p 8088:8088 cybermaggedon/hadoop:2.8.0

  # Slaves
  docker run --rm -e DAEMONS=nodemanager -e RESOURCEMANAGER_HOSTNAME=hadoop01 \
      -e NAMENODE_URI=hdfs://hadoop01:9000 -i -t --name=hadoop02 \
      --link hadoop01:hadoop01 -P cybermaggedon/hadoop:2.8.0
  docker run --rm -e DAEMONS=nodemanager -e RESOURCEMANAGER_HOSTNAME=hadoop01 \
      -e NAMENODE_URI=hdfs://hadoop01:9000 -i -t --name=hadoop03 \
      --link hadoop01:hadoop01 -P cybermaggedon/hadoop:2.8.0
