Dmitriy Pavlov commented on IGNITE-8119:
----------------------------------------
Why do you expect Ignite should operate on broken PDS storage?
> NPE on clear DB and unclear WAL/WAL_ARCHIVE
> -------------------------------------------
>
> Key: IGNITE-8119
> URL: https://issues.apache.org/jira/browse/IGNITE-8119
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.4
> Reporter: Alexander Belyak
> Priority: Major
> Attachments: ClearTest.java, ClearTestP.java
>
>
> 1) Start grid (1 node will be enought), activate it and populate some data
> 2) Stop node and clear db folder
> 3) Start grid and activate it
> Expected result:
> Error about inconsistent storage configuration with/without start node with
> such store
> Actual result:
> Exchange-worker on node stop with NPE, this can hang whole cluster from
> complete any PME operations.
> {noformat}
> Failed to reinitialize local partitions (preloading will be stopped):
> GridDhtPartitionExchangeId [topVer=AffinityTopologyVersion [topVer=1,
> minorTopVer=1], ...
> java.lang.NullPointerException
