如果我有一个十六进制的行键，例如 x00\x01 ，我如何在 HBASE shell 中 get ？

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

您可以使用普通的get 命令引用它，但是十六进制键必须用双引号，单引号不起作用：

例如你会使用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}

有时你的十六进制行键会包含一个'"'。即)\x93\x83\x5C\xD0\xD5B\xC4\x83q\xD3z\x17"\xC1\xFF只需用'\'转义里面的双引号，即)\x93\x83\x5C\xD0\xD5B\xC4\x83q\xD3z\x17\"\xC1\xFF
有没有办法在 Java 中实现这一点。我在这里@@stackoverflow.com/questions/57391102/… 尝试过，但仍在试图弄清楚如何做到这一点。
