> Goals:
> Metrics Collector is placed on a less busy master
> AMS HBase root dir is set to a separate mount if available, WARN user if the default
mount point say "/" is selected when some other partition is available.
> Set hbase.tmpdir to separate mount or "/" (different from rootdir) if such an option
is available.
> Fine tune memory settings for clusters under 100 nodes but that have resource avaialble,
we see that sometimes 50 node settings are too conservative for a 40 node cluster but they
are fine for a 10 node.
> Tune the metrics collection frequency (This is experimental item, I am not sure this
will help in reducing load)
