[jira] [Updated] (IGNITE-14828) No fallback to full rebalance after exception on historical

     [ https://issues.apache.org/jira/browse/IGNITE-14828?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mirza Aliev updated IGNITE-14828:
---------------------------------
    Description: 
We have noticed that in some cases when we handle demand message in {{GridDhtPartitionSupplier.java}} it is possible for some reasons that
{code:java}
iter = grp.offheap().rebalanceIterator(demandMsg.partitions(), demandMsg.topologyVersion());
{code}
throw an exception. In that case, rebalance should switch to full, but the code has a bug and {{remainingParts}} has been filed after rebalance iterator has been created
{code:java}
                for (int i = 0; i < histMap.size(); i++) {
                    int p = histMap.partitionAt(i);

                    remainingParts.add(p);
                }
{code}
That means that we lost partitions that meant to be rebalanced by historical rebalance.

  was:Will be filled soon
