--------------------------------------------
Summary: Wal isn't enabled for some caches after cancelling of
rebalance
Key: IGNITE-17911
URL: https://issues.apache.org/jira/browse/IGNITE-17911
Project: Ignite
Issue Type: Task
Reporter: Aleksandr Polovtcev
Assignee: Aleksandr Polovtcev
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.
