    <value>true</value>
  </property>

b) Restart hbase

 

[ nitin@nitin-ubuntu:~ # ] sudo /usr/lib/hbase/bin/stop_hbase.sh

[ nitin@nitin-ubuntu:~ # ] sudo /usr/lib/hbase/bin/start_hbase.sh

Step 2 :-

Take a Snapshot

[ nitin@nitin-ubuntu:~ # ] hbase shell

hbase> snapshot 'MY_TABLE', 'SNAP_MYTABLE'

Step 3 :-

Listing Snapshots

[ nitin@nitin-ubuntu:~ # ] hbase shell

hbase> list_snapshots

Step 4 :-

Deleting Snapshots

[ nitin@nitin-ubuntu:~ # ] hbase shell

hbase> delete_snapshot 'SNAP_MYTABLE'

Step 5 :-

Clone a table from snapshot

[ nitin@nitin-ubuntu:~ # ] hbase shell

hbase> clone_snapshot 'SNAP_MYTABLE', 'NEW_TABLE'

Step 6 :-

Export to another cluster:-

[ nitin@nitin-ubuntu:~ # ]  hbase  org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot SNAP_Target_toys_Prods -copy-to hdfs://CLUSTER2:8020/hbase
