JanusGraph is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time. 3 | 4 | Instructions on how to add JanusGraph to Apache Ambari or Hortonworks Data Platform(HDP) as a service can be found below. 5 | 6 | 7 | - To download the service and link it to Ambari run the following commands 8 | ``` 9 | VERSION=`hdp-select versions | head -n1 | cut -d'.' -f1,2` 10 | git clone https://github.com/chupman/janusgraph-ambari-service.git /var/lib/ambari-server/resources/stacks/HDP/$VERSION/services/JANUSGRAPH 11 | ``` 12 | 13 | ``` 14 | sudo service ambari-server restart 15 | ``` 16 | ## Service Installation 17 | - Once the ambari-server service has restarted login into the webui and click on the Actions dropdown on the lower lefthand side and select '+Add Service'. 18 | Click on the checkbox next to Janusgraph and then press next. 19 | Currently JanusGraph needs to be located on the same host as Solr. If solr is not yet installed you'll need to install it through the [mpack](https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_solr-search-installation/content/ch_hdp-search-install-ambari.html). 20 | 21 | - Click add service from the actiosn dropdown: 22 | ![Image](../master/screenshots/add_service.png?raw=true) 23 | - The add service wizard will show all available services: 24 | ![Image](../master/screenshots/add_service_wizard.png?raw=true) 25 | - Scroll down and check the box nex to JanusGraph and click next. If solr is not already installed it will be automatically added as a dependancy: 26 | ![Image](../master/screenshots/add_service_wizard_select_JG.png?raw=true) 27 | - The assign masters screen shows you where all of your existing services are installed. You'll need to scroll down to find JanusGraph: 28 | ![Image](../master/screenshots/assign_masters.png?raw=true) 29 | - Select the host you want to install Janusgraph on from the dropdown. It's reccomended to install it on the same host as solr for performance: 30 | ![Image](../master/screenshots/add_service_wizard_JG.png?raw=true) 31 | - There is currently no JanusGraph client so the Assign Slaves and Clients screen will be bypassed. Next you'll be able to customize your installation. No user supplied values are required: 32 | ![Image](../master/screenshots/customize_services.png?raw=true) 33 | - You can customize environment details like target directories and your gremlin server configuration: 34 | ![Image](../master/screenshots/customize_services_jg-env.png?raw=true) 35 | - Click Deploy on the Installation review screen: 36 | ![Image](../master/screenshots/review.png?raw=true) 37 | - Once the JanusGraph installation has been successfully complete the sevices view should look like this: 38 | ![Image](../master/screenshots/janusgraph_installed.png?raw=true) 39 | -------------------------------------------------------------------------------- /alerts.json: -------------------------------------------------------------------------------- 1 | { 2 | "JANUSGRAPH": { 3 | "JANUSGRAPH_SERVER": [ 4 | { 5 | "name": "janusgraph", 6 | "label": "janusgraph server", 7 | "description": "This host-level alert is triggered if the JanusGraph Server Instance is unreachable.", 8 | "interval": 1, 9 | "scope": "ANY", 10 | "source": { 11 | "type": "SCRIPT", 12 | "path": "JANUSGRAPH/package/alerts/alert_check_janusgraph_server.py", 13 | "parameters": [ 14 | { 15 | "name": "janusgraph.run.dir", 16 | "display_name": "Run Directory", 17 | "value": "{{janusgraph-env/janusgraph_pid_dir}}", 18 | "type": "STRING", 19 | "description": "The directory where the JanusGraph server process places its PID files." 20 | }, 21 | { 22 | "name": "janusgraph.install.dir", 23 | "display_name": "Janusgraph Install Directory", 24 | "value": "{{janusgraph-env/janusgraph_install_dir}}", 25 | "type": "STRING", 26 | "description": "The directory where the JanusGraph dist is located." 27 | }, 28 | { 29 | "name": "janusgraph.user", 30 | "display_name": "Janusgraph User", 31 | "value": "janusgraph", 32 | "value": "{{janusgraph-env/janusgraph_user}}", 33 | "type": "STRING", 34 | "description": "User who starts the JanusGraph Server process" 35 | } 36 | ] 37 | } 38 | } 39 | ] 40 | } 41 | } 42 | -------------------------------------------------------------------------------- /configuration/gremlin-server.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 22 | 23 | 24 | 25 | content 26 | Configuration for JanusGraph Server 27 | 28 | host: {{janusgraph_host}} 29 | port: {{janusgraph_server_port}} 30 | scriptEvaluationTimeout: 300000 31 | serializedResponseTimeout: 300000 32 | 33 | channelizer: org.apache.tinkerpop.gremlin.server.channel.HttpChannelizer 34 | graphs: { 35 | graph: conf/janusgraph-hbase-solr.properties, 36 | graphSpark: conf/hadoop-graph/hadoop-gryo.properties} 37 | plugins: 38 | -
