Cloudera folks -  Any guideline on setting the appropriate threshold for Monitor Swap Memory Usage?  The default warning of Any seems heavy-handed in modern Linux systems, where it may make sense to swap even when lots of memory is still free (e.g. http://unix.stackexchange.com/questions/2658/why-use-swap-when-there-is-more-than-enough-free-space-... )

 

Thanks,

Miles
