h3. Validation after node restart

Every deployment unit with nodeDURecord.status == DEPLOYED must be validated in order to prevent a situation when the deployment unit was undeployed and then deployed again with the same deployment unit ID and version but with different content (some kind of [ABA problem|https://en.wikipedia.org/wiki/ABA_problem]). The nodeDURecord.depOpId and corresponding clusterDURecord.depOpId must be the same. Otherwise the deployment unit should be removed from the node.

 

For every nodeDURecord(depOpId, UPLOADING) record corresponding clusterDURecord(depOpId, DEPLOYED) or clusterDURecord(depOpId, UPLOADING) must exist. Otherwise the invalid deployment unit must be removed from the node.

 

For every nodeDURecord(depOpId, DEPLOYED) record corresponding clusterDURecord(depOpId, DEPLOYED) or clusterDURecord(depOpId, UPLOADING) must exist. Otherwise the invalid deployment unit must be removed from the node.


For every nodeDURecord(depOpId, OBSOLETE) or nodeDURecord(depOpId, REMOVING) record corresponding clusterDURecord(depOpId, OBSOLETE) or clusterDURecord(depOpId, REMOVING) must exist. Otherwise the invalid deployment unit must be removed from the node.
