Bernardo Gomez Palacio created MESOS-813:
--------------------------------------------
Summary: As a CLI User I should be able get the available
resources of a Mesos Cluster.
Key: MESOS-813
URL: https://issues.apache.org/jira/browse/MESOS-813
Project: Mesos
Issue Type: Improvement
Reporter: Bernardo Gomez Palacio
Priority: Minor
Rationale:
As a CLI User I should be able to know how much memory/resources the Cluster
has available before activating a framework. The Use Case arises when several
CLI Users are interacting with Shark while the Cluster is already running
additional frameworks. Ideally the CLI Users knows the available memory such
that they can set a sensitive SPARK_MEM value. This will help reduce the number
of Shark Queries hanging waiting for resources that they not necessarily
require.
Implementation suggestion.
Will be simple to follow the mesos-ps script example to read the
master/stats.json endpoint to present such metrics. The script could be
mesos-stats and receive the specific metric you are interested in, should
default to all.
Potential enhancement could be an argument that loops the command such that we
have a continuos feed of the stats in the cli.
