Yan Xu commented on MESOS-2776:
-------------------------------
h2. State
h3. Resources model change
Current resources are exported like this:
{noformat:title=}
resources: {
cpus: 0.210000000000001,
disk: 389429,
ephemeral_ports: "[32768-57344]",
mem: 57402,
ports: "[31697-31708, 31966-31969, 31971-32000, 31500-31695, 31907-31964,
31761-31905, 31083-31428, 31710-31759, 31000-31081, 31430-31498]"
},
{noformat}
Revocable resources can look like this:
{noformat:title=}
resources: {
cpus{REV}: 0.210000000000001,
disk{REV}: 389429,
ephemeral_ports{REV}: "[32768-57344]",
mem{REV}: 57402,
ports{REV}: "[31697-31708, 31966-31969, 31971-32000, 31500-31695, 31907-31964,
31761-31905, 31083-31428, 31710-31759, 31000-31081, 31430-31498]"
},
{noformat}
a la https://reviews.apache.org/r/34676
h4. Notes
- *Regular resources will look the same*.
- Since regular resources and revocable resources can't be merged, the
'resources' dict will separately list them all.
This will change the resources representations used by different models in
state.json:
Slave: used_resources, offered_resources
Task: resources
Framework: offered_resources
h3. Framework model change: capabilities
{noformat:title=}
capabilities : {
revocable: true
}
{noformat}
Changes can be made just to the JOSN model. Framework struct in Master doesn't
need to change.
> Master should expose metrics about oversubscribed resources
