A. Building & Installing Metadata
=================================
0. Prerequisites
------------------
You would need the following installed:
* JDK 1.7
* Maven 3.x
1. Building Metadata
--------------------
Building DGI from the source repository
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* git clone git@github.com:hortonworks/metadata.git metadata
* cd metadata
* export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m" && mvn clean install
2. Deploying DGI
---------------------
Once the build successfully completes, artifacts can be packaged for deployment.
* mvn clean assembly:assembly -DskipTests -DskipITs
Tar can be found in {project dir}/target/apache-metadata-${project.version}-bin.tar.gz
Tar is structured as follows
|- bin
|- metadata-start.sh
|- metadata-stop.sh
|- conf
|- application.properties
|- graph.properties
|- log4j.xml
|- docs
|- server
|- webapp
|- metadata.war
|- README
|- NOTICE.txt
|- LICENSE.txt
|- DISCLAIMER.txt
|- CHANGES.txt
3. Installing & running DGI
--------------------------------
a. Installing DGI
~~~~~~~~~~~~~~~~~~~~~~
* tar -xzvf apache-metadata-${project.version}-bin.tar.gz
* cd metadata-${project.version}
b. Starting DGI Server
~~~~~~~~~~~~~~~~~~~~~~~~~
* bin/metadata-start.sh
c. Using DGI
~~~~~~~~~~~~~~~
* Verify if the server is up and running
curl -v http://localhost:21000/api/metadata/admin/version
{"Version":"v0.1"}
* List the types in the repository
curl -v http://localhost:21000/api/metadata/types
{"list":["biginteger","short","byte","int","string","bigdecimal","boolean","date","double","long","float"],"requestId":"902580786@qtp-1479771328-0"}
* List the instances for a given type
curl -v http://localhost:21000/api/metadata/entities?type=hive_table
{"requestId":"788558007@qtp-44808654-5","list":["cb9b5513-c672-42cb-8477-b8f3e537a162","ec985719-a794-4c98-b98f-0509bd23aac0","48998f81-f1d3-45a2-989a-223af5c1ed6e","a54b386e-c759-4651-8779-a099294244c4"]}
curl -v http://localhost:21000/api/metadata/entities/list/hive_db
* Search for entities (instances) in the repository
curl -v http://localhost:21000/api/metadata/discovery/search/dsl?query="from hive_table"
d. Stopping DGI Server
~~~~~~~~~~~~~~~~~~~~~~~~~
* bin/metadata-stop.sh
