在HBase中，要查看表數據的總數，可以通過Java API或者HBase Shell命令來實現。
Configuration config = HBaseConfiguration.create();
Connection connection = ConnectionFactory.createConnection(config);
TableName tableName = TableName.valueOf("your_table_name_here");
Table table = connection.getTable(tableName);
Scan scan = new Scan();
ResultScanner scanner = table.getScanner(scan);
int count = 0;
for (Result result : scanner) {
count++;
}
System.out.println("Total number of rows in the table: " + count);
scanner.close();
table.close();
connection.close();
count 'your_table_name_here'
以上兩種方法都可以幫助您查看HBase表的數據總數。
