I have a Hbase table X and I want to create an exact copy of it and name it Y. Could someone let me know how it is possible?

Thanks

Assuming you want to copy the table on the same cluster you can use HBase snapshots in the hbase shell you can

snapshot 'sourceTable', 'sourceTable-snapshot'
clone_snapshot 'sourceTable-snapshot', 'newTable'
