Base Storage Layer:
The base storage layer defines where job results are written by default.
| Info |

NOTE: The base storage layer should be enabled and configured during initial installation. After the base storage layer has been configured, it cannot be switched to another environment. |
| Tip | |

Tip: The
webapp.storageProtocol=s3 should still be specified to write results to S3. |
Access and Browse data - S3:
Optionally, you can enable access and the ability to browse your S3 datastore.
JDBC Sources:
Independent of these storage options, you can access database table data through JDBC datastores. See Enable Relational Connections.
HDFS Only
Base Storage Layer: HDFS
Access and Browse data - S3: Off

Hybrid Hadoop-based Deployment
Base Storage Layer: HDFS
Access and Browse data - S3: On
Notes:
This deployment is recommended for the following:
- On-premises Hadoop clusters that require access to remote S3 data
- Hadoop clusters hosted in the cloud that require access to remote S3 data and want to continue to use HDFS as an output location
In this scenario, the
has access to HDFS and Hive data on the same cluster, as well as access to the remote S3 buckets that have been enabled for the platform.D s platform
- HDFS remains the output location for all job results, profiles, and uploads.
Amazon-based Deployment
Base Storage Layer: S3
Access and Browse data - S3: On
Notes:
This deployment is recommended for Hadoop clusters that are completely hosted in AWS and must use S3 as the base storage for all data including job results, profiles, and uploads.
