This weblog submit gives an summary of the HBase to CDP Operational Database (COD) migration course of.
CDP Operational Database allows builders to shortly construct future-proof functions which are architected to deal with knowledge evolution. It helps builders automate and simplify database administration with capabilities like auto-scale and is totally built-in with Cloudera Knowledge Platform (CDP). For extra data and get began with COD, discuss with Getting Began with Cloudera Knowledge Platform Operational Database (COD).
Now you can migrate your current 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 distinct 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 a must to evaluate and carry out all the required knowledge migration preparation duties. The mandatory duties rely in your particular cluster setup.
For extra data, in regards to the listed prerequisite duties, see HBase migration stipulations.
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 knowledge
- Optionally, verifying the migration
Replication setup consists of configuring the beforehand talked about Cloudera Replication Plugin, configuring the HBase and HDFS companies, and utilizing the ReplicationSetupTool instrument.
As soon as the replication is ready up, you may migrate your knowledge. To begin the method you first need to 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 knowledge.
With a purpose to confirm that replication was profitable and that the information in your supply and goal clusters are in sync you should utilize the HashTable/CldrSyncTable instrument.
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.

*Observe: Knowledge replication supported by Cloudera Replication Plug-in is just not a full in-place improve. Full in-place improve is supported solely to CDP Personal Cloud Base.
