Upgrading an HDFS HA Configuration to the Latest Release

Upgrading to CDH 5


NFS shared storage is not supported in CDH 5. If you are using an HDFS HA configuration using NFS shared storage, disable the configuration before you begin the upgrade. You can redeploy HDFS HA using Quorum-based storage either before or after the upgrade.

To upgrade an HDFS HA configuration using Quorum-base storage from CDH 4 to the latest release, follow the directions for upgrading a cluster under Upgrading to the Latest Version of CDH 5.
