Configuring HBase Snapshots
HBase snapshot support enables you to take a snapshot of a table without much impact
on RegionServers, because snapshot, clone, and restore operations do not involve data
copying. In addition, exporting a snapshot to another cluster has no impact on
About HBase snapshots HBase snapshots allow you to clone a table without making data copies, and with minimal impact on RegionServers. Exporting the table to another cluster does not have any impact on the RegionServers. Configure snapshots Snapshots are enabled by default, you must disable snapshots if you do not intend to use it. Snapshots do not affect HBase performance if they are not used. Manage HBase snapshots using Cloudera Manager For HBase services, you can use the Table Browser tab to view the HBase tables associated with a service on your cluster. You can view the currently saved snapshots for your tables, and delete or restore them. Store HBase snapshots on Amazon S3 HBase snapshots can be stored on the cloud storage service Amazon S3. Manage HBase snapshots using the Command Line You can manage snapshots by using the HBase Shell, or you can use a shell script. Export a snapshot to another cluster You can export any snapshot from one cluster to another. Exporting the snapshot copies the table's hfiles, logs, and the snapshot metadata, from the source cluster to the destination cluster. Snapshot failures Region moves, splits, and other metadata actions that happen while a snapshot is in progress can cause the snapshot to fail. The software detects and rejects corrupted snapshot attempts.
