Upcoming Renaming of Memory Statistics from /monitor/statistics.json (MESOS-2104)

[Chi Zhang <ch...@gmail.com>]

If you are not using mem_rss_bytes, mem_file_bytes and mem_anon_bytes
from /monitor/statistics.json prior to 0.23.0, you can stop reading.

Hi Community,

I would like to send out an update from MESOS-2014:

Targeted for 0.23.0:

mem_total_bytes will be introduced to replace mem_rss_bytes.
mem_rss_bytes will replace mem_anon_bytes, which will be removed in 0.24.0.
mem_cache_bytes will be introduced to replace mem_file_bytes, which
will be removed in 0.24.0.

The overall timeline for this change is planned as:

0.22.0 (latest)              0.23.0 (next)
                  0.24.0
mem_rss_bytes     ->   mem_total_bytes
  -> mem_total_bytes
mem_anon_bytes  ->  mem_rss_bytes, mem_anon_bytes       -> mem_rss_bytes
mem_file_bytes      ->  mem_cache_bytes, mem_file_bytes     -> mem_cache_bytes

For more information behind the change, please refer to MESOS-2104 and
