> We need query admin utility to list running queries, get a query detail, or kill a specified running query. The utility may have the following form:
> {code:title=query list}
> $ bin/tajo admin -list
> query id                  start time                 query
> q_xxx_xxx running  2014-01-02T13:45:00 select a,b,c ... ...
> q_xxx_xxx running  2014-01-02T13:47:00 select count(distinct ...
> {code}
> {code:title=query kill}
> $ bin/tajo admin -kill q_xxx_xxxx
> q_xxx_xxxx has been killed.
> {code}
> {code:title=query detail}
> $ bin/tajo admin -desc q_xxx_xxxx
> query id: q_xxx_xxxx
> submit user: hyunsik
> start time: 2014-01-01T13:46:50
> running time: 36 sec
> query statement: 
> SELECT a,b,c
