Summary: Add unit validation after node restart
Key: IGNITE-19518
URL: https://issues.apache.org/jira/browse/IGNITE-19518
Project: Ignite
Issue Type: New Feature
Reporter: Mikhail Pochatkin
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.
