Presto is a tool designed to efficiently query vast amounts of data using distributed queries.

We will be installing Presto in single server mode, Access Hive and then add worker node.

Cross query - RBDMS, Hive, NoSql

Tutorial

**Java 8 must **

Install - link (for the latest versions)

wget https://repo1.maven.org/maven2/com/facebook/presto/presto-server/0.122/presto-server-0.122.tar.gz

tar xvfz presto-server-0.122.tar.gz

Let's start with Single node setup (master and worker on the same node)

cd presto-server-0.122

mkdir etc

[root@ns2 presto-server-0.122]# cd etc/

mkdir catalog and we will create 3 files as shown below

[root@ns2 etc]# ls

catalog config.properties jvm.config log.properties node.properties

[root@ns etc]# cat config.properties

coordinator=true

node-scheduler.include-coordinator=true

http-server.http.port=9080

query.max-memory=10GB

query.max-memory-per-node=1GB

discovery-server.enabled=true

discovery.uri=http://ns2:9080

[root@ns2 etc]# cat log.properties

com.facebook.presto=INFO

[root@ns2 etc]# cat node.properties

node.environment=production

node.id=presto1

node.data-dir=/var/presto/data

Details on the properties are here

Now , let's create hive properties file (I have create hive.properties already)

cd catalog/

[root@ns2 catalog]# ls

hive.properties jmx.properties

[root@ns2 catalog]# cat hive.properties

connector.name=hive-hadoop2

hive.metastore.uri=thrift://ns3:9083

hive.config.resources=/etc/hadoop/conf/core-site.xml,/etc/hadoop/conf/hdfs-site.xml

All set to start presto server

[root@ns2 bin]# pwd

/root/presto-server-0.122/bin

[root@ns2 bin]# nohup ./launcher run &

[1] 11722

[root@ns2 bin]# nohup: ignoring input and appending output to `nohup.out'

[root@ns2 bin]# tail -f nohup.out

last line will be

2015-10-18T16:49:49.935-0400 INFO main com.facebook.presto.metadata.CatalogManager -- Added catalog hive using connector hive-hadoop2 --

2015-10-18T16:49:50.005-0400 INFO main com.facebook.presto.server.PrestoServer ======== SERVER STARTED ========

hit http://host:9080

Let's access Hive tables

Download presto cli ( link for the latest release)

mv presto-cli-0.122-executable.jar presto

[root@ns2 bin]# ./presto --server ns2:9080 --catalog hive

presto> show tables from default;

Create a table in Hive

Presto UI

click one of the queries to check the stats.

Click Execution link to get execution plan

Let's add worker node and remove master from the worker

Node name - ns4

Repeat installation steps in new node as mentioned above then make following changes

/root/presto-server-0.122/etc

[root@ns4 etc]# cat config.properties

coordinator=false

http-server.http.port=9080

query.max-memory=10GB

query.max-memory-per-node=1GB

discovery.uri=http://ns2:9080 (It points to master server)

[root@ns4 etc]# cat node.properties (node.id needs to be unique)

node.environment=production

node.id=presto2

node.data-dir=/var/presto/data

[root@ns4 etc]# cd ..

[root@ns4 presto-server-0.122]# cd bin/

[root@ns4 bin]# nohup ./launcher run &

[root@ns02 bin]# ./presto --server ns2:9080 --catalog hive

Happy Hadooping!!!

Hi Neeraj,

I am able to install presto but my queries are failing. Did you face similar error before?

presto:default> show tables;
Query 20181130_001533_00002_5gf9c failed: 10.xxx.xx.xx: null

presto:default> exit

Caused by: org.apache.thrift.transport.TTransportException: 10.xxx.xx.xx:: null
	at com.facebook.presto.hive.HiveMetastoreClientFactory.rewriteException(HiveMetastoreClientFactory.java:58)
	at com.facebook.presto.hive.HiveMetastoreClientFactory.access$000(HiveMetastoreClientFactory.java:33)
