如何使用HBASE Shell获取一行,其中rowkey是十六进制的？

Question

如果我有一个十六进制的rowkey,比如x00\x01,我get在HBASE shell中怎么做？

hbase(main):004:0> scan 'tsdb-tree'
ROW                 COLUMN+CELL
\x00\x01            column=t:tree, timestamp=1379421652764, value={"name":"...

Answer 1

您可以使用普通get命令引用它,但十六进制密钥必须是双引号,单引号将不起作用:

例如,您将使用get 'tsdb-tree', "\x00\x01":

hbase(main):016:0> scan 'tsdb-tree'
ROW                                                                       COLUMN+CELL                                                                                                                                                                                                             
 \x00\x01                                                                 column=t:tree, timestamp=1379421652764, value={"name":"TestTree1","description":"","notes":"","strictMatch":false,"created":0,"enabled":false,"storeFailures":false}                                                    
 \x00\x01                                                                 column=t:tree_rule:0:0, timestamp=1379371753132, value={"type":"METRIC","field":"host","regex":"","separator":"","description":"","notes":"","level":0,"order":0,"treeId":1,"customField":"","regexGroupIdx":0,"displayF

 \x00\x02                                                                 column=t:tree, timestamp=1379372909057, value={"name":"testTree2","description":"","notes":"","strictMatch":false,"created":0,"enabled":false,"storeFailures":false}
