Subject [jira] [Commented] (SPARK-17454) Add option to specify Mesos resource offer constraints
Date Fri, 23 Sep 2016 14:58:20 GMT


Chris Bannister commented on SPARK-17454:

The scheduler will write the to mesos disk sandbox if LOCAL_DIRS is not set, see SPARK-9708.
Not all nodes are the same, some have small fast disks, some have large slow disks or some
just have different amount of space available due to other tasks running on them.

> Currently the driver will accept offers from Mesos which have enough ram for the executor
and until its max cores is reached. There is no way to control the required CPU's or disk
for each executor, it would be very useful to be able to apply something similar to spark.mesos.constraints
to resource offers instead of attributes on the offer.
