presto
```
* config carbondata-connector for presto
- First:compile carbondata-presto integration module
+ Firstly: Compile carbondata, including carbondata-presto integration
module
```
$ git clone https://github.com/apache/carbondata
- $ cd carbondata/integration/presto
- $ mvn clean package
+ $ cd carbondata
+ $ mvn -DskipTests -P{spark-version}
-Dspark.version={spark-version-number} -Dhadoop.version={hadoop-version-number}
clean package
+ ```
+ Replace the spark and hadoop version with you the version you used in
your cluster.
+ For example, if you use Spark2.1.0 and Hadoop 2.7.3, you would like to
compile using:
+ ```
+ mvn -DskipTests -Pspark-2.1 -Dspark.version=2.1.0 -Dhadoop.version=2.7.3
clean package
+ ```
+
+ Secondly: Create a folder named 'carbondata' under $PRESTO_HOME$/plugin
and
+ copy all jar from
carbondata/integration/presto/target/carbondata-presto-x.x.x-SNAPSHOT
+ to $PRESTO_HOME$/plugin/carbondata
+
+ Thirdly: Create a carbondata.properties file under
$PRESTO_HOME$/etc/catalog/ containing the following contents:
```
- Second:create one folder "carbondata" under ./presto-server-0.166/plugin
- Third:copy all jar from
./carbondata/integration/presto/target/carbondata-presto-x.x.x-SNAPSHOT
- to ./presto-server-0.166/plugin/carbondata
+ connector.name=carbondata
+ carbondata-store={schema-store-path}
+ ```
+ Replace the schema-store-path with the absolute path the directory which
is the parent of the schema.
+ For example, if you have a schema named 'default' stored under
hdfs://namenode:9000/test/carbondata/,
+ Then set carbondata-store=hdfs://namenode:9000/test/carbondata
+
+ If you changed the jar balls or configuration files, make sure you have
dispatch the new jar balls
+ and configuration file to all the presto nodes and restart the nodes in
the cluster. A modification of the
+ carbondata connector will not take an effect automatically.
