I have two different scenarios or behaviors, none is working as I would expect. One is what I am experiencing in my project (whole project) and the other one is what I am experiencing when creating a toy project trying to reproduce it. In both cases, I am using Ignite 2.7.6.
This is the code I am using for the toy project ( Github:Code <https://github.com/jrecuerda/IgnitePlayground/tree/master/PartitionLossPolicy> ). It is written in Kotlin but I think it is quite simple so it should be understandable even if you don't know Kotlin. Steps to reproduce it: - Run 5 nodes NodeStartup.kt - Run Client.kt which activate the cluster and insert some data into an IgniteCache<Long, Long> - Shut down 2 out of the 5 Nodes. - Run Client.kt again. * Calling to lostPartitions() returns an empty list, I would expect it to return some partitions since the backup is set to one and two nodes were turned off. * When trying to put data into the cache, even when the partitionLossPolicy is set to IGNORE, throws: Exception in thread "main" org.apache.ignite.cache.CacheServerNotFoundException: Failed to map keys for cache (all partition nodes left the grid). at org.apache.ignite.internal.processors.cache.GridCacheUtils.convertToCacheException(GridCacheUtils.java:1321) at org.apache.ignite.internal.processors.cache.IgniteCacheProxyImpl.cacheException(IgniteCacheProxyImpl.java:1758) at org.apache.ignite.internal.processors.cache.IgniteCacheProxyImpl.put(IgniteCacheProxyImpl.java:1108) at org.apache.ignite.internal.processors.cache.GatewayProtectedCacheProxy.put(GatewayProtectedCacheProxy.java:820) at jrh.ClientKt.insertData(Client.kt:30) at jrh.ClientKt.main(Client.kt:42) at jrh.ClientKt.main(Client.kt) Caused by: class org.apache.ignite.internal.cluster.ClusterTopologyServerNotFoundException: Failed to map keys for cache (all partition nodes left the grid). at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridNearAtomicSingleUpdateFuture.mapSingleUpdate(GridNearAtomicSingleUpdateFuture.java:562) at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridNearAtomicSingleUpdateFuture.map(GridNearAtomicSingleUpdateFuture.java:454) at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridNearAtomicSingleUpdateFuture.mapOnTopology(GridNearAtomicSingleUpdateFuture.java:443) at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridNearAtomicAbstractUpdateFuture.map(GridNearAtomicAbstractUpdateFuture.java:248) at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridDhtAtomicCache.update0(GridDhtAtomicCache.java:1153) at org.apache.ignite.internal.processors.cache.distributed.dht.atomic.GridDhtAtomicCache.put0(GridDhtAtomicCache.java:611) at org.apache.ignite.internal.processors.cache.GridCacheAdapter.put(GridCacheAdapter.java:2449) at org.apache.ignite.internal.processors.cache.GridCacheAdapter.put(GridCacheAdapter.java:2426) at org.apache.ignite.internal.processors.cache.IgniteCacheProxyImpl.put(IgniteCacheProxyImpl.java:1105) ... 4 more Thank you! -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
