Migrate historical data with HBase snapshot

Prerequisites

• Ensure network connectivity between the source cluster, the target cluster, and LTS.

• Add the data sources for the source and target instances. For more information, see Add a Lindorm wide table data source.

Considerations

• This migration solution supports only HBase 2.x.

• Before migration, verify the HDFS capacity of the target instance. Ensure that sufficient capacity is available to prevent task failure.

Create a migration task

1. Log on to the LTS console.

2. In the navigation pane on the left, choose Lindorm/HBase Migration > Historical Data Migration.

3. Click Create Task.

4. Specify the Source Cluster and Target Cluster parameters, and select the Table Structure Migration checkbox.

   Note

   If you select the Table Structure Migration checkbox, the system creates tables with the same schema and partition information in the target cluster. If a table already exists in the target cluster, the system skips that table.

5. In the Tables to Synchronize/Migrate section, specify each table and its snapshot using the format: <table_name>{"snapshotName":"<snapshot_name>"}. For example: table1{"snapshotName":"table1-snapshot"}. To migrate multiple tables, add each entry on a new line.

   Note

   For more information about HBase Snapshot, see Use HBase Snapshots.

6. Click Create to create the task.
