Installation

Requirements

• MapD
• Presto v0.170

Setup

1. Clone this repository and cd into it

git clone git@github.com:NVIDIA/presto-mapd-connector.git
cd presto-mapd-connector

2. Create a lib directory and copy the mapd jdbc jar into it (mapdjdbc-1.0-SNAPSHOT-jar-with-dependencies.jar)

mkdir lib
cp $MAPD_HOME/mapdjdbc-1.0-SNAPSHOT-jar-with-dependencies.jar lib/

3. Build/package the project

mvn package

4. Copy the jar to your presto plugin directory

mkdir $PRESTO_HOME/plugin/mapdjdbc
cp presto-mapd-jdbc-1.0-jar-with-dependencies.jar $PRESTO_HOME/plugin/mapdjdbc

5. Make a mapdjdbc.properties file

mkdir -p $PRESTO_HOME/etc/catalog && touch $PRESTO_HOME/etc/catalog/mapdjdbc.properties

6. In the properties file, enter your credentials to connect to mapd...

connector.name=mapdjdbc
connection-url=jdbc:mapd:localhost:9091:mapd
connection-user=<username>
connection-password=<password>

7. You can now start mapd and presto with the ability to query mapd from presto!
