Eric Yang commented on CHUKWA-447:
----------------------------------
The expected period parameter is in seconds, but the code is running as:
{noformat}
timer.schedule(execTimer, 0L, period);
{noformat}
Hence, it's running 1000 times more frequent than expected.
> Load increased by 50% when using ExecAdaptor instead of
> org.apache.hadoop.chukwa.inputtools.plugin.metrics.Exec+FileTailingAdaptor

> While I am coming up a fix for CHUKWA-446, I notice the load average
> increased by ExecAdaptor. There is probably something that could be improved
> to reduce the cost of ExecAdaptor.
