[英]Read the values with knowing ColumnFamily and Column qualifier with thrift in a hbase dataset
How can I just read the rows, with a specific ColumnFamily and Column Qualifier? 如何使用特定的ColumnFamily和Column Qualifier读取行?
So, I know, ColumnFamily = "R" and Column = "r000003vl_*". 因此,我知道ColumnFamily =“ R”和Column =“ r000003vl_ *”。 How can I get all the values?
如何获得所有值?
仅扫描列族R和带有“ r000003vl_ *”的列值过滤器,如果行具有列键值,则将返回所有行的列数据。
use ColumnPrefixFilter to scan column family R. 使用ColumnPrefixFilter扫描列族R。
