Maksim Timonin updated IGNITE-18782:
------------------------------------
Ignite Flags: (was: Docs Required,Release Notes Required)
> Snapshot restore might fail after cluster become active due to transition
> state
> -------------------------------------------------------------------------------
>
> Key: IGNITE-18782
> URL: https://issues.apache.org/jira/browse/IGNITE-18782
> Project: Ignite
> Issue Type: Bug
> Reporter: Maksim Timonin
> Priority: Major
>
> `ign.cluster().state(ClusterState.ACTIVE)` activates cluster but after this
> method returns some grid nodes might be in transition state -
> `ctx.state().clusterState().transition() == true`.
> Ignite nodes checks the transition state before restoring snapshot, and then
> restoring procedure might fail.
> Also, it looks like `GridClusterStateProcessor#publicApiState(boolean
> waitForTransition)` doesn't check transition state. Example is
> IgniteClusterSnapshotRestoreSelfTest#testUserClassRestored - it's required to
> explicitly check transition to start restoring snapshot, usage of the
> publicApiState call doesn't help. Maybe bug here?
> There are some possible ways to fix it:
> # `state(ClusterState.ACTIVE)` should return after transition has fully
> completed
> # Snapshot restoring should await while transition state finished.
