> Key: IGNITE-19042
> URL: https://issues.apache.org/jira/browse/IGNITE-19042
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Uttsel
> Assignee: Sergey Uttsel
> Priority: Major
> Labels: ignite-3
> Time Spent: 3h
> Remaining Estimate: 0h

> h3. Motivation
> NullPointerException in log on start the first node in the cluster if
> DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleUp and
> DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleDown are 0.
> How to reproduce:
> # Set DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleUp = 0 and
> DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleDown = 0.
> # Start the test which starts the node. For example
> ItTablesApiTest#testAddIndex.
> # See NullPointerException in the log.
> {code:java}
> Caused by: java.lang.NullPointerException at
> java.base/java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.java:108)
> at org.apache.ignite.internal.util.ByteUtils.fromBytes(ByteUtils.java:152)

> The root cause is zoneDataNodesKey, zoneScaleUpChangeTriggerKey,
> zoneScaleDownChangeTriggerKey of zones are not initialized on node start if
> vaultMgr.get(zonesLogicalTopologyKey()) is null.
> *Definition of Done*
> zoneDataNodesKey, zoneScaleUpChangeTriggerKey, zoneScaleDownChangeTriggerKey
> are initialized on the node start.
