> Key: IGNITE-6767
> URL: https://issues.apache.org/jira/browse/IGNITE-6767
> Project: Ignite
> Issue Type: Bug
> Security Level: Public(Viewable by anyone)
> Components: cache
> Affects Versions: 2.1
> Reporter: Vyacheslav Koptilin
> Attachments: GridCacheNearClientHitTest.java
>
>
> {{IgniteCache.localPeek(key, PeekMode.NEAR)}} always returns 'null' if the
> node, which owns the primary partition for the given key, left the cluster,
> even if {{IgniteCache.get(key)}} was called.
> How to reproduce:
> # start two server nodes.
> # create partitioned or atomic cache and populate data.
> # start client node with near cache configured.
> # perform {{IgniteCache.get(key)}} and check that
> {{IgniteCache.localPeek(key, PeekMode.NEAR)}} returns not null value.
> # stop server node which owns primary partition for the given {{key}}.
> # perform {{IgniteCache.get(key)}}.
> # after that {{IgniteCache.localPeek(key, PeekMode.NEAR)}} always returns
> null value.
