* HDDS-14496-zdu: HDDS-16153. DatanodeDetails should use HDDSVersion instead of int (apache#10994) HDDS-15549. Recon's INITIAL_VERSION should not have an upgrade action (apache#10935) HDDS-14753. Do not prematurely serialize client version (apache#10936) HDDS-15885. SCM should validate software versions of peers before accepting finalize command (apache#10783) HDDS-15641. SCM should send write pipeline version with DatanodeDetails on block allocation (apache#10878) Conflicts: hadoop-hdds/common/src/main/java/org/apache/hadoop/hdds/protocol/DatanodeDetails.java hadoop-hdds/common/src/main/java/org/apache/hadoop/hdds/scm/pipeline/Pipeline.java hadoop-hdds/common/src/test/java/org/apache/hadoop/hdds/protocol/TestDatanodeDetails.java hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/HddsDatanodeService.java hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/helpers/DatanodeIdYaml.java hadoop-hdds/server-scm/src/main/java/org/apache/hadoop/hdds/scm/protocol/StorageContainerLocationProtocolServerSideTranslatorPB.java hadoop-ozone/common/src/main/java/org/apache/hadoop/ozone/om/protocolPB/OzoneManagerProtocolClientSideTranslatorPB.java hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/ozone/client/rpc/TestBlockDataStreamOutput.java hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/request/file/OMRecoverLeaseRequest.java

DatanodeDetails#currentVersionis passed from Datanodes through SCM to clients to indicate the Datanode's server version. Once ZDU is finalized, this value should be the apparent version of the Datanode instead of a static software version. A new abstract method is added toComponentVersionManagerto handle this and implemented for every component in this PR. On Datanodes, this method is called in the register and heartbeat endpoint tasks to provide SCM with the most up to date current version.Additionally,
DatanodeDetails#currentVersionis currently persisted into the Datanode'sdatanode.idyaml file, but never used. When Datanodes finalize, the current version they report to clients will increase, and this location will become stale. To keep it from diverging we should stop persisting this value in thedatanode.idfile.What is the link to the Apache JIRA
