Azure Blob Storage

Warning

The legacy Windows Azure Storage Blob driver (WASB) has been deprecated. Azure Data Lake Storage Gen2 (ABFS) has numerous benefits over WASB that recommend migration.

Before deploying the Denodo Embedded MPP on Azure Kubernetes Service check Denodo Embedded MPP Azure Checklist to make sure you have everything you need.

Provide the Azure credentials to the kubectl create secret command before the Embedded MPP is deployed:

ENV Variable

Description

WASB_STORAGE_KEY

Azure Blob Storage Key

 
   kubectl create secret generic mpp-credentials
   --from-literal=METASTORE_DB_PASSWORD=hive
   --from-literal=WASB_STORAGE_KEY=abfsstoragekey

It’s also necessary to set true the objectStorage.azure.sharedKey.enabled and add the Azure Blob Storage Account in the objectStorage.azure.sharedKey.account properties in values.yaml.

As Azure Blob Storage is deprecated, the necessary properties are not included in the prestocluster/hive-metastore/conf/core-site.xml and prestocluster/presto/conf/core-site.xml so you need to modify fs.azure.account.key property from:

<property>
    <name>fs.azure.account.key.{{ .Values.objectStorage.azure.sharedKey.account }}.dfs.core.windows.net</name>
    <value>${env.ABFS_STORAGE_KEY}</value>
</property>

To:

<property>
    <name>fs.azure.account.key.{{ .Values.objectStorage.azure.sharedKey.account }}.blob.core.windows.net</name>
    <value>${env.WASB_STORAGE_KEY}</value>
</property>

Run helm install sentence

helm install prestocluster prestocluster/
