Subject IO problem
Date Wed, 14 Mar 2012 06:08:47 GMT
       I m running coprocessor aggregation for some million rows. When
execution cpu is waiting for IO for long time and doesn't give the result.
The ganglia cpu status shows that 25% is utilized for user process and 50%
is waiting for IO. No other process is running at that time. What might be
the problem?
