Ankur Chauhan updated SPARK-6707:
---------------------------------
Description:
Currently, the mesos scheduler only looks at the 'cpu' and 'mem' resources when
trying to determine the usablility of a resource offer from a mesos slave node.
It may be preferable for the user to be able to ensure that the spark jobs are
only started on a certain set of nodes (based on attributes).
For example, If the user sets a property, let's say
{code}spark.mesos.constraints{code} is set to
{code}tachyon=true;us-east-1=false{code}, then the resource offers will be
checked to see if they meet both these constraints and only then will be
accepted to start new executors.
