--------------------------------------------
The same exception occurs on finishing exchange after calling
{{ignite.destroyCache(s)}}
> NPE in GridDhtLocalPartition.cacheMapHolder()
> ---------------------------------------------

> Key: IGNITE-7579
> URL: https://issues.apache.org/jira/browse/IGNITE-7579
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.3
> Reporter: Alexandr Kuramshin
> Priority: Major
>
> The following scenario may occurs:
> # Multiple nodes construct an inactive cluster.
> # Cluster activation performed.
> # Some nodes fail activation.
> # On the other nodes caches will be stopped.
> # NPE occurs as a consequence of {{GridDhtPreloader.evictPartitionAsync()}}
> {noformat}
> Partition eviction failed, this can cause grid hang.
> java.lang.NullPointerException: null

> {noformat}
> # Drop failed nodes from the cluster.
> # The latter activation will be successful.
> # PDS seems to be corrupted by the cause of NPE.
