> Currently, max value for -Xmn parameter is bounded by (hbase-rs-2.2.json):
> {code}
>             "hbase_regionserver_xmn_max": "512",
> {code}
> During multiple troubleshooting sessions with customers, we (thanks to [~vrodionov])
found that this limit is too low for large heap size.
> This JIRA is to increase the limit to 4000 MB.
