As to your suggestion, how do I complete following codes?
or any better codes would be great!
HTable table = new HTable(config, "user");
Get g = new Get(Bytes.toBytes("U1"));
Result r = table.get(g);
for loop--- //I don't know how many articles the user have.
byte [] t = r.getValue(Bytes.toBytes("chapter"), Bytes.toBytes("?"));
//t1
byte [] c = r.getValue(Bytes.toBytes("chapter"), Bytes.toBytes("?"));
//c1
byte [] d = r.getValue(Bytes.toBytes("chapter"), Bytes.toBytes("?"));
//d1
end loop---
Thank you very much

Please respond to
hbase-user
create user as your row key. then create a columnFamily called chapter. For
each column entry store a json string which will contain title,content and
creation date. Using google's gson marsheller to convert your POJO object
to
JSON string.
U1 chapter:{t1,c1,d1},chapter:{t2,c2,d2}... etc...
let me know if it helps.
