Version recommendation for DLM and HDP
You must ensure that you are using versions of DLM App, DLM Engine, HDP, and Ambari that are supported together.
It is strongly recommended that you install the latest version of DLM, to take advantage of the latest functionality and the stability updates.
DataPlane Platform and DLM App should be the latest version. DLM capabilities supported here are the features of the minimum DLM Engine version.
DLM Engine should be on the latest version available for the HDP version that you have installed in your environment. You can upgrade HDP to the version that the latest DLM Engine version requires to perform in a seamless manner.
DLM 1.4.0 version is compatible with HDP 18.104.22.1680 and HDP 22.214.171.124 releases. HDP 126.96.36.1990 release has fixes in different components of HDP like Hive, Ranger, and Atlas to enable the DLM functionality. If you are performing replication using Google Cloud Storage and if you are upgrading from less than HDP 188.8.131.520 release, you must perform a full cluster upgrade to HDP 184.108.40.2060 release.
If you are already on HDP 220.127.116.110 release, you need not perform a full cluster upgrade.
DLM 1.4.0 only supports on-premise to on-premise replication with HDP 18.104.22.1680 release as source and HDP 22.214.171.124 as destination.
If you are on an earlier release of HDP, use a standard full upgrade to HDP 126.96.36.1990 release. Please reach out to Hortonworks support team to get HDP 188.8.131.520.
