MUDROD

Mining and Utilizing Dataset Relevancy from Oceanographic Datasets to Improve Data Discovery and Access

license Build Status Docker Pulls codecov Quality Gate

MUDROD is a semantic discovery and search project funded by NASA AIST (NNX15AM85G).

Software requirements:

  • Java 8
  • Git
  • Apache Maven 3.X
  • Elasticsearch v5.X
  • Kibana v4
  • Apache Spark v2.0.0
  • Apache Tomcat 7.X

Installation

Docker Container

We strongly advise all users to save time and effort by consulting the Dockerfile documentation for guidance on how to quickly use Docker to deploy Mudrod.

From source

  1. Ensure you have Elasticsearch running locally and that the configuration in config.xml reflects your ES cluster.
  2. Update the svmSgdModel configuration option in config.xml. There is a line in config.xml that looks like
    <para name="svmSgdModel">file://YOUNEEDTOCHANGETHIS</para>
    
    It needs to be changed to an absolute filepath on your system. For example:
    <para name="svmSgdModel">file:///Users/user/githubprojects/mudrod/core/src/main/resources/javaSVMWithSGDModel</para>
    
  3. (Optional) Depending on your computer's configuration you might run into an error when starting the application: “Service 'sparkDriver' could not bind on port 0”. The easiest fix is to export the environment variable SPARK_LOCAL_IP=127.0.0.1 and then start the service.
$ git clone https://github.com/mudrod/mudrod.git
$ cd mudrod
$ mvn clean install
$ cd service
$ mvn tomcat7:run

You will now be able to access the Mudrod Web Application at http://localhost:8080/mudrod-service. N.B. The service should not be run this way in production.

Deploying to Apache Tomcat (or any other Servlet container)

Once you have built the codebase as above, merely copy the genrated .war artifact to the servlet deployment directory. In Tomcat (for example), this would look as follows

$ cp mudrod/service/target/mudrod-service-${version}-SNAPSHOT.war $CATALINA_HOME/webapps/

Once Tomcat hot deploys the .war artifact, you will be able to browse to the running application similar to what is shown above http://localhost:8080/mudrod-service
