如果我有一个十六进制的rowkey,比如x00\x01
,那我在HBASE shell中如何get
?
hbase(main):004:0> scan 'tsdb-tree'
ROW COLUMN+CELL
\x00\x01 column=t:tree, timestamp=1379421652764, value={"name":"...
答案 0 :(得分:20)
您可以使用普通的get
命令引用它,但十六进制密钥必须是双引号,单引号不起作用:
例如,您可以使用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
ormat":""}
\x00\x02 column=t:tree, timestamp=1379372909057, value={"name":"testTree2","description":"","notes":"","strictMatch":false,"created":0,"enabled":false,"storeFailures":false}

hbase(main):017:0> get 'tsdb-tree', "\x00\x01"
