For example: System.out.println(Bytes.toString(entry.getKey())); -----邮件原件----- 发件人: beeshma r [mailto:[email protected]] 发送时间: 2014年12月10日 2:24 收件人: [email protected] 主题: to get all column qualifiers Hi i want to get all column qualifiers and corresponding cell values for the Rowkey for example below is table structure hbase(main):002:0> scan "people" ROW COLUMN+CELL [email protected] column=colmn_fam:[email protected], timestamp=14160315498 33, value=1 [email protected] column=colmn_fam:[email protected], timestamp=141590081652 2, value=\x00\x00\x00\x01 [email protected] column=colmn_fam:[email protected], timestamp=1415900817028, va lue=\x00\x00\x00\x01 [email protected] column=colmn_fam:[email protected], timestamp=1416031549845 , value=1 [email protected] column=colmn_fam:[email protected], timestamp=1415900817017, value=\x00\x00\x00\x01 [email protected] column=colmn_fam:[email protected], timestamp=14160315498 40, value=1 [email protected] column=colmn_fam:[email protected], timestamp=1416148432981, value=1 [email protected] column=colmn_fam:[email protected], timestamp=1416031549850, value=1 [email protected] column=colmn_fam:[email protected], timestamp=1416722434614, v alue=1 [email protected] column=colmn_fam:[email protected], timestamp=1415900817022, value=\x00\x00\x00\x01 [email protected] column=colmn_fam:[email protected], timestamp=1415900817035, v alue=\x00\x00\x00\x01 for key =>[email protected] i have to get all columnqualifiers in "colmn_fam" column family so what is the way to get that?i tried below samples but i didnt get what i expect..please suggest the best way to get that here i tried some methods Get get_colums=new Get(ROWKEY); Result result_of_coumns=testTable.get(get_colums); Map <byte[],byte[]> family=result_of_coumns.getFamilyMap(colmnfamily); for (Map.Entry<byte[],byte[]> entry:family.entrySet()) { System.out.println(entry.getKey()); System.out.println(entry.getValue()); } O/P [B@35e023f0 [B@e577d32 LiST METHOD List <String> mail_list = new ArrayList<String>(); Result result_of_coumns=testTable.get(get_colums); for(Byte kv:result_of_coumns.getRow()) { System.out.println(kv.toString()); mail_list.add(kv.toString()); } for(String temp:mail_list) { System.out.println(temp.toString()); } O/P 97 121 121 111 64 103 109 97 105 108 46 99 111 109 Thanks Beesh
