> Index rebuild future is created too late
> ----------------------------------------

> Key: IGNITE-7569
> URL: https://issues.apache.org/jira/browse/IGNITE-7569
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.4
> Reporter: Alexey Goncharuk
> Assignee: Alexey Goncharuk
> Priority: Major
> Fix For: 2.5
>
>
> rebuildIndexesIfNeeded is called before the exchange future onDone method,
> which may be too late in a distributed case: a node may complete a local
> exchange and send a compute job to a remote node. In this case, if the job
> checks the index rebuild future, it may observe {{null}}.
> To fix this, we should create the future in beforeExchange, and complete it
> after the rebuild is finished.
