------------------------------------------
Summary: AssertionError: Unexpected rebalance on rebalanced cluster
Key: IGNITE-15033
URL: https://issues.apache.org/jira/browse/IGNITE-15033
Project: Ignite
Issue Type: Bug
Reporter: Vladislav Pyatkov
Assignee: Vladislav Pyatkov
It has low probably that partition state restored incorrectly when a cache is
starting with data on disk.
The issue happened because cluster can save the partition meta page during it
state is still restored.
The code is shown below (GridCacheOffheapManager.java):
{code:java}
@Override public Map<Integer, Long> restorePartitionStates {
//Here the metapage was restored from disk, but it state is not recovery in
GridDhtLocalPartition.
part.dataStore().init();
... // Here another thread will be able to execute saveStoreMetadata and set
an incorrect state on the metapage.
//State will be recovered only here.
long pageAddr = pageMem.writeLock(grp.groupId(), partMetaId, partMetaPage);
try {
int stateId = io.getPartitionState(pageAddr);
updateState(part, stateId);
}
finaly {
pageMem.writeUnlock(grp.groupId(), partMetaId, partMetaPage, null, changed);
}
}
{code}
