Create a dedicated\n*network* for the cluster to run on.\n\nFurthermore is useful to fix the container *name* and the container\n*hostname* to the same value. This way every container will able to\nresolve itself with the same name as other container.\n\nLastly is useful to set the *domainname* equal to the name of the\n*network* and use *FQDN* to reference the various services.\n\nWith the specified setup is possible you'll be able to access the\nweb-interfaces of the various components without the annoying problem\nof unresolved links (provided that you setup a dns solution to resolve\ncontainer names and configure static routing if using\n*docker-machine*).\n\n## Components\n\n### namenode\n\nThe *hadoop-namenode* image starts an Hadoop NameNode. (single instance)\n\nAdditional environment variables:\n\n* `CLUSTER_NAME`: name of the *HDFS* cluster (used during the initial\nformatting)\n\nVolumes:\n\n* `/hadoop/dfs/name`: *HDFS* filesystem name directory\n\nMandatory configuration:\n\n* `CLUSTER_NAME`: cluster name\n\n*Docker-compose* template:\n\n namenode:\n image: uhopper/hadoop-namenode\n hostname: namenode\n container_name: namenode\n domainname: hadoop\n net: hadoop\n volumes:\n - :/hadoop/dfs/name\n environment:\n - GANGLIA_HOST=\n - CLUSTER_NAME=\n\nOnce running you can connect to `http://:50070` to see\nthe webui.\n\n### datanode\n\nThe *hadoop-datanode* image starts an Hadoop DataNode. (multiple instances)\n\nVolumes:\n\n* `/hadoop/dfs/data`: *HDFS* filesystem data directory\n\nMandatory configuration:\n\n* `CORE_CONF_fs_defaultFS`: *HDFS* address (i.e. `hdfs://:8020`)\n\n*Docker-compose* template:\n\n datanode1:\n image: uhopper/hadoop-datanode\n hostname: datanode1\n container_name: datanode1\n domainname: hadoop\n net: hadoop\n volumes:\n - :/hadoop/dfs/data\n environment:\n - GANGLIA_HOST=\n - CORE_CONF_fs_defaultFS=hdfs://:8020\n\n### resourcemanager\n\nThe *hadoop-resourcemanager* image starts an Hadoop\nResourceManager. (single instance)\n\nMandatory configuration:\n\n* `CORE_CONF_fs_defaultFS`: *HDFS* address (i.e. `hdfs://:8020`)\n\n*Docker-compose* template:\n\n resourcemanager:\n image: uhopper/hadoop-resourcemanager\n hostname: resourcemanager\n container_name: resourcemanager\n domainname: hadoop\n net: hadoop\n environment:\n - GANGLIA_HOST=\n - CORE_CONF_fs_defaultFS=hdfs://:8020\n - YARN_CONF_yarn_log___aggregation___enable=true\n\nOnce running you can connect to `http://:8088` to see\nthe webui.\n\n### nodemanager\n\nThe *hadoop-nodemanager* image starts an Hadoop NodeManager. (multiple\ninstances) \n\nMandatory configuration:\n\n* `CORE_CONF_fs_defaultFS`: *HDFS* address (i.e. `hdfs://:8020`)\n* `YARN_CONF_yarn_resourcemanager_hostname`: *resourcemanager* host\n\n*Docker-compose* template:\n\n nodemanager1:\n image: uhopper/hadoop-nodemanager\n hostname: nodemanager1\n container_name: nodemanager1\n domainname: hadoop\n net: hadoop\n environment:\n - GANGLIA_HOST=\n - CORE_CONF_fs_defaultFS=hdfs://:8020\n - YARN_CONF_yarn_resourcemanager_hostname=\n - YARN_CONF_yarn_log___aggregation___enable=true\n - YARN_CONF_yarn_nodemanager_remote___app___log___dir=/app-logs\n\n### spark\n\nThe *hadoop-spark* image is an utility container which provides a\nSpark environment configured for the *hadoop* cluster.\n\nThe image itself doesn't specify any command since no service are\nexposed. You are expected to specify it yourself via `docker run\nuhopper/hadoop-spark `.\n\nA common approach is to keep the container alive using `tail -f\n/var/log/dmesg` as command and then connect to it via `docker exec -ti\nspark bash` to have a *spark* environment.\n\nMandatory configuration:\n\n* `CORE_CONF_fs_defaultFS`: *HDFS* address (i.e. `hdfs://:8020`)\n* `YARN_CONF_yarn_resourcemanager_hostname`: *resourcemanager* host\n\n*Docker-compose* template:\n\n spark:\n image: uhopper/hadoop-spark\n hostname: spark\n container_name: spark\n domainname: hadoop\n net: hadoop\n environment:\n - CORE_CONF_fs_defaultFS=hdfs://namenode:8020\n - YARN_CONF_yarn_resourcemanager_hostname=resourcemanager\n command: tail -f /var/log/dmesg\n","has_starred","hub_user","immutable_tags_settings",{"_75":11,"_76":77},"enabled","rules",[78],".*","is_automated","permissions",{"_82":21,"_83":11,"_84":11},"read","write","admin","user","storage_size",617096522,"orgData","recentTags",[91,129],{"_92":44,"_93":94,"_95":96,"_97":98,"_99":100,"_50":118,"_119":94,"_120":33,"_121":56,"_57":122,"_123":124,"_125":109,"_126":118,"_127":66,"_128":21},"content_type","creator",2268057,"full_size",335507974,"id",30842484,"images",[101],{"_102":103,"_104":105,"_106":107,"_108":109,"_110":111,"_112":113,"_114":107,"_115":-5,"_116":96,"_63":66,"_117":-5},"architecture","amd64","digest","sha256:1d76ab320477cdbd8a7b16f6a1742222d7a950180c7047ae0efe3830d977e7b6","features","","last_pulled","2026-10-08T20:15:23.739010825Z","last_pushed","2019-03-24T22:39:55Z","os","linux","os_features","os_version","size","variant","2019-03-24T22:39:54.269761Z","last_updater","last_updater_username","media_type","latest","repository",5723317,"tag_last_pulled","tag_last_pushed","tag_status","v2",{"_92":44,"_93":94,"_95":130,"_97":131,"_99":132,"_50":137,"_119":94,"_120":33,"_121":56,"_57":138,"_123":124,"_125":135,"_126":137,"_127":66,"_128":21},335545613,30842401,[133],{"_102":103,"_104":134,"_106":107,"_108":135,"_110":136,"_112":113,"_114":107,"_115":-5,"_116":130,"_63":66,"_117":-5},"sha256:89ec05df86c575364a15dc76c9a9de21d5b8713cd29e8bec6b4c24804f17b4eb","2026-10-08T20:03:58.039092657Z","2018-07-12T01:43:36Z","2018-07-12T01:43:35.452701Z","2.8.4","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","showSbxLogoOverride","sbxTrademarkText","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"selectedTag","attestationsUrl","routes/_layout.r.$namespace.$reponame.tags",{"_38":152,"_159":160,"_146":173,"_174":11},{"_40":153,"_42":154,"_45":46,"_47":48,"_49":11,"_50":51,"_52":53,"_54":155,"_57":35,"_32":33,"_58":59,"_60":44,"_61":62,"_63":64,"_65":66,"_67":-5,"_68":62,"_69":70,"_71":11,"_72":33,"_73":156,"_79":21,"_80":158,"_85":33,"_86":87},[],[44],[56],{"_75":11,"_76":157},[78],{"_82":21,"_83":11,"_84":11},"tags",{"_161":162,"_163":-5,"_164":-5,"_165":166},"count",2,"next","previous","results",[167,170],{"_92":44,"_93":94,"_95":96,"_97":98,"_99":168,"_50":118,"_119":94,"_120":33,"_121":56,"_57":122,"_123":124,"_125":109,"_126":118,"_127":66,"_128":21},[169],{"_102":103,"_104":105,"_106":107,"_108":109,"_110":111,"_112":113,"_114":107,"_115":-5,"_116":96,"_63":66,"_117":-5},{"_92":44,"_93":94,"_95":130,"_97":131,"_99":171,"_50":137,"_119":94,"_120":33,"_121":56,"_57":138,"_123":124,"_125":135,"_126":137,"_127":66,"_128":21},[172],{"_102":103,"_104":134,"_106":107,"_108":135,"_110":136,"_112":113,"_114":107,"_115":-5,"_116":130,"_63":66,"_117":-5},[],"canDeleteTags","actionData","errors"]
