hbase - 行キーが 16 進数である HBASE シェルで行を取得するにはどうすればよいですか?

Question

のような 16 進数の行キーがある場合、HBASE シェルでそれをx00\x01行うにはどうすればよいgetですか?

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

Answer 1

通常のgetコマンドを使用して参照できますが、16 進数のキーは二重引用符で囲む必要があり、単一引用符は機能しません。

たとえば、次のように使用しますget 'tsdb-tree', "\x00\x01"。

hbase(main):016:0> scan 'tsdb-tree'
ROW                                                                       COLUMN+CELL
