Updating Big Data Service Clusters

Update Big Data Service clusters and software from the Cluster details page.

Prerequisites:

If you have created a Big Data Service cluster with the NAT gateway option set to false as described in Creating Network Resources, be sure the VCN you're using has a service gateway configured with explicit route added to allow access to the OCI Object storage bucket. For detailed information, see Service Gateway.
To allow all access to YUM repositories for each region, the following access must be granted on all nodes.
Exact YUM URL to enable connection to for each region: https://yum.<region-identifier>.<realm-domain>
Region identifiers for OC1 can be found at: Regions and Availability Domains
Realm domain for OC1 is oci.oraclecloud.com.
To install an OS update there must be at least 25 GB of free space on the root volume on each cluster node.

Software Version

You must keep the software versions of the services current to maintain version currency and we recommend that you apply the most recent update as soon as it becomes available.
We are not responsible for performance, functionality, availability or security issues experienced with Big Data Service that might result from running earlier versions.

Updates for Big Data Service are rolled out periodically. We recommend that you apply the most recent updates within three to four months to maintain support of the product. Delaying updates causes your service to be unsupported for future updating and upgrade.
Most update operations are rolling operations, so your service continues to function with very little interruption during the update process.
Updates are cumulative, that is, the latest update includes all earlier updates.
