Subject [jira] [Updated] (SPARK-3795) Add scheduler hooks/heuristics for adding and removing executors
Date Sat, 04 Oct 2014 19:11:33 GMT

     [ https://issues.apache.org/jira/browse/SPARK-3795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Patrick Wendell updated SPARK-3795:
-----------------------------------
    Description: To support dynamic scaling of a Spark application, Spark's scheduler will
need to have hooks around explicitly decommissioning executors. We'll also need basic heuristics
governing when to start/stop executors based on load. An initial goal is to keep this very
simple.  (was: To support dynamic scaling of a Spark application, Spark's scheduler will need
to have hooks around explicitly decommissioning executors. )
