This weblog publish offers an summary of the HBase to CDP Operational Database (COD) migration course of.
CDP Operational Database allows builders to rapidly construct future-proof functions which might be architected to deal with information evolution. It helps builders automate and simplify database administration with capabilities like auto-scale and is totally built-in with Cloudera Information Platform (CDP). For extra data and get began with COD, confer with Getting Began with Cloudera Information Platform Operational Database (COD).
Now you can migrate your present HBase workloads to COD* with the Cloudera Replication plugin. Cloudera Replication plugin permits communication between the kerberized cluster in COD and the supply cluster which may be unsecured or have a unique Kerberos realm.
The next is an summary of the HBase migration steps:
Put together for the migration
Earlier than you begin the migration course of it’s important to evaluation and carry out all the required information migration preparation duties. The required duties rely in your particular cluster setup.
For extra data, concerning the listed prerequisite duties, see HBase migration conditions.
Migrate your HBase to CDP Operational Database (COD)
The HBase to COD migration course of has three phases:
- Organising the replication
- Utilizing a snapshot emigrate information
- Optionally, verifying the migration
Replication setup consists of configuring the beforehand talked about Cloudera Replication Plugin, configuring the HBase and HDFS providers, and utilizing the ReplicationSetupTool device.
As soon as the replication is about up, you may migrate your information. To start out the method you first must disable the replication peer earlier than taking a snapshot. After disabling the replication peer you may create, export, confirm and restore a snapshot. After the snapshot is restored on the goal cluster, allow the replication peer on the supply cluster to start replicating information.
With a view to confirm that replication was profitable and that the info in your supply and goal clusters are in sync you should use the HashTable/CldrSyncTable device.
For extra details about the way to migrate your HBase from CDH or HDP to CDP Operational Database (COD), see the HBase migration from CDH/HDP to COD CDP Public Cloud migration information.

*Be aware: Information replication supported by Cloudera Replication Plug-in shouldn’t be a full in-place improve. Full in-place improve is supported solely to CDP Non-public Cloud Base.
