Run Presto on Azure HDInsight

TL;DR

Run a custom Script Action on existing or new HDInsight hadoop cluster (version 3.5 or above) with following as your bash script URI and run it on "HEAD" and "WORKER":

https://raw.githubusercontent.com/hdinsight/presto-hdinsight/master/installpresto.sh

Now you can SSH to your cluster and start using presto:

presto --schema default

This will connect to hive metastore via hive connector. On a N worker node cluster, you will have N-2 presto worker nodes and 1 coordinator node. The setup also configures TPCH connector, so you can run TPCH queries directly.

If you want to configure additional connectors, you can pass the catalog configurations as a parameter to the custom action script. The syntax is ‘connector1’ : [‘key1=value1’, ‘key2=value2’..], ‘connector2’ : [‘key1=value1’, ‘key2=value2’..] as described in presto-yarn. So, the following string as a parameter will add sqlserver and DocDB connectors with its configurations (notice the "" around the full string):

" 'cosmosdb': ['connector.name=mongodb','mongodb.seeds=test.documents.azure.com:10255','mongodb.credentials=testuser:secretpassword@prestocollection','mongodb.ssl.enabled=true'],'sqlserver': ['connector.name=sqlserver','connection-url=jdbc:sqlserver://testsqlserver.database.windows.net:1433;database=testdb;user=testuser@testserver;password=secretpassword;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;', 'connection-user=testuser','connection-password=secretpassword'] "

Airpal

To optionally install airpal,

1. SSH to the cluster and run the following command to find out the address of the presto server

   sudo slider registry  --name presto1 --getexp presto
   

   You will see output like following, note the IP:Port.

   {
     "coordinator_address" : [ {
       "value" : "10.0.0.11:9090",
       "level" : "application",
       "updatedTime" : "Sat Feb 25 05:45:14 UTC 2017"
     }
   

2. Click here the below link to add an edge node to the cluster where airpal is going to be installed. Provide Clustername, EdgeNodeSize and PrestoAddress (noted above).

To access the airpal, go to azure portal, your cluster and navigate to Applications and click on portal. You have to login with cluster login credentials.

FAQ

Is this Microsoft supported product?

No.

What cluster types are valid?

The script supports only hadoop clusters. Other cluster types (Spark, Kafka, Storm, Secure Hadoop etc.) are not supported.

My installation failed. Where are the logs?

You can check the script action logs in your default storage account under <STORAGE_ACCOUNT_NAME>/<DEFAULT_CONTAINER_NAME>/custom-scriptaction-logs/<CLUSTER_NAME>/<DATE> . For more information checkout the "Access logs from the default storage account " section from HDInsight documentation.

Does it work with Windows Azure Storage Blob (WASB)?

Yes.

Does it work with Azure Data Lake Store (ADLS)?

Yes. Following are the instrcutions :

1. Go to Ambari -> HDFS -> Configs -> Advanced -> Custom core-site.

2. Click on "Add Property" to add following proerties to core-site. The details of this configuration can be found here:

    fs.adl.impl=org.apache.hadoop.fs.adl.AdlFileSystem
    fs.AbstractFileSystem.adl.impl=org.apache.hadoop.fs.adl.Adl
    dfs.adls.oauth2.access.token.provider.type=ClientCredential
    dfs.adls.oauth2.refresh.url=https://login.microsoftonline.com/YOUR_AZURE_AD_TENANT_ID/oauth2/token
    dfs.adls.oauth2.client.id=YOUR_AZURE_SERVICE_PRINCIPAL_ID
    dfs.adls.oauth2.credential=YOUR_AZURE_SERVICE_PRINCIPAL_PASSWORD
   

3. Restart the required services by going to Ambari -> Actions -> "Restart All Required"

4. Now run the presto script action from the azure portal.

How do I customize presto installation?

If you want to customize presto (change the memory settings, change connectors etc.),

1. Create a presto cluster without customization following the steps above.

2. SSH to the cluster and specify your customizations. The configuration file is located at /var/lib/presto/presto-hdinsight-master/appConfig-default.json

3. Stop and destroy the current running instance of presto.

   sudo slider stop presto1 --force
   sudo slider destroy presto1 --force
   

4. Start a new instance of presto with the customizations.

   sudo slider create presto1 --template /var/lib/presto/presto-hdinsight-master/appConfig-default.json --resources /var/lib/presto/presto-hdinsight-master/resources-default.json
   

5. Wait for the new instance to be ready and note presto coordinator address.

   sudo slider registry --name presto1 --getexp presto
