> WAL can be disabled during a rebalance if a node does not own any partitions. When stopping a node, a shutdown hook is used, which calls {{IgniteionEx#stop}} with the {{cancel}} flag set to {{true}}. This wakes up the checkpoint thread and starts doing a checkpoint, which creates a checkpoint start marker. However, since the {{cancel}} flag was set to {{true}}, {{Checkpointer#writePages}} finishes immediately and the checkpoint end marker is not created.
> This means that we have not enabled WAL again, since the rebalance was interrupted, and we created a checkpoint start marker, but not the end marker. This leads to the node being started in maintenance mode.
