I don't know the impact when this setting is too high. Apparently the default in Ubuntu is 60. I only noticed the warning because I was looking at log files randomly. I'm wondering if this check is important enough to be done when the shell starts and to display the error to the console at that time.
This was the message: [server.Accumulo] WARN : System swappiness setting is greater than ten (60) which can cause time-sensitive operations to be delayed. Accumulo is time sensitive b ecause it needs to maintain distributed lock agreement.
