Upgrading Kudu

Before upgrading, you should read the release notes for the version of Kudu that you are about to install. Note that rolling upgrades are not supported. Shut down all Kudu services before you begin upgrading the software.

  Important: If you have previously installed the beta IMPALA_KUDU service, make sure you remove it from your cluster before you proceed.

Upgrade Kudu using Cloudera Manager

  Warning:
  • You must upgrade Kudu before you upgrade CDH. Failure to do so will result in Impala queries returning the following error: 
    Query Status: Unable to open scanner: Remote error: unsupported feature flags
  • If you are upgrading from Kudu 1.2.0 / CDH 5.10.x, you must upgrade both Kudu and CDH parcels (or packages) at the same time. If you upgrade Kudu but do not upgrade CDH, new Kudu features such as Security will not be available. Note that even though you might be able to see the updated configuration options for Kudu security in Cloudera Manager, configuring them will have no effect.

To use Cloudera Manager to upgrade Kudu using parcels or packages, use the following instructions. If you do not use Cloudera Manager, see Upgrade Kudu Using the Command Line.
