Enum Constant Detail

STABLE

public static final UpgradeState STABLE

Stable state. This is the default state that the cluster is in when there are no upgrades taking place.

READY_TO_UPGRADE

public static final UpgradeState READY_TO_UPGRADE

Cluster nodes are ready to be brought down and upgraded.

MIXED

public static final UpgradeState MIXED

At least one node has been upgraded and re-joined the cluster with a higher build number. READY_TO_UPGRADE still applies.

READY_TO_RUN_UPGRADE_TASKS

public static final UpgradeState READY_TO_RUN_UPGRADE_TASKS

All nodes have re-joined the cluster with a higher build number. All nodes are on the same build number. The upgrade is ready to be approved and the upgrade tasks can be run after approval.

RUNNING_UPGRADE_TASKS

public static final UpgradeState RUNNING_UPGRADE_TASKS

The delayed upgrade tasks are currently running on a node. Once this is done the state will switch back to STABLE.

UPGRADE_TASKS_FAILED

public static final UpgradeState UPGRADE_TASKS_FAILED

Running the upgrade tasks has failed. Errors have to be acknowledged before the state can transition back to READY_TO_RUN_UPGRADE_TASKS.
