--------------------------------
and, please check also my "BigTable Simulation Code Source".
you can download here.

it will be used on mapreduce.
I expect can recording of multiple <K,V> maps from Once-through process to
parsing a tab delimited text file.
Table t = new Table();
t.Create("webtable", new String[]{"anchor","language"});
//Write a new anchor, language
RowMutation r1 = new RowMutation(t.OpenOrDie("webtable"),
"udanax.org");
r1.Set("anchor:hadoop.co.kr","hadoop korean user
group");
r1.Set("anchor:joinc.co.kr","joinc");
r1.Set("language:kr", "euc-kr");
r1.Set("anchor:hadoop.co.kr", "hadoop");
r1.Set("anchor:naver.com", "naver");
Operation op = new Operation();
op.Apply(r1);
//Reading from table
Scanner stream = new Scanner("webtable");
stream.FetchColumnFamily("anchor");
stream.Lookup("udanax.org");
while(stream.next())
(
System.out.print("(RowName):");
System.out.print(stream.RowName());
System.out.print(" (ColumnName):");
System.out.print(stream.ColumnName());
System.out.print(" (Value):");
System.out.println(stream.Value());
)
stream.close();
