What is the method for deleting a record in HBase?

To delete a record in HBase, you can achieve this by calling an instance of the Delete class. The steps to delete the data are as follows:

1. Create an instance of the Delete class, with the constructor requiring the RowKey parameter to be passed in.

Delete delete = new Delete(Bytes.toBytes("rowkey"));

1. Optionally, you can set a timestamp for the Delete instance to delete specific versions of data. By default, the delete operation will remove all versions of data.

delete.setTimestamp(timestamp);

1. Optionally, you can specify column families and qualifiers for the Delete operation in order to delete specific columns.

delete.addColumn(Bytes.toBytes("columnFamily"), Bytes.toBytes("columnQualifier"));

1. Optionally, you can set column families for a Delete operation to remove all columns within the column family.

delete.addFamily(Bytes.toBytes("columnFamily"));

1. Optionally, you can set a timestamp range for the Delete instance to remove data within a specified timestamp range.

delete.setTimeRange(minTimestamp, maxTimestamp);

1. Execute the delete operation using the delete() method of the Table instance.

Table table = connection.getTable(TableName.valueOf("table"));
table.delete(delete);

Please make sure that the HBase table exists and that a connection has been established before deleting data.
