Subject [jira] [Commented] (MESOS-4837) Ignore DOWN machine in "/machine/schedule"
Date Thu, 03 Mar 2016 02:32:18 GMT

    [ https://issues.apache.org/jira/browse/MESOS-4837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15177020#comment-15177020
] 

Klaus Ma commented on MESOS-4837:
---------------------------------

Further more, if the only update one slave's maintenance schedule, all slave will be updated
to UP and trigger allocate(slaveId). Refer to the code in {{master/http.cpp}}: https://github.com/apache/mesos/blob/master/src/master/http.cpp#L1996

One proposed solution is to only handle {{DRAIN}} here, to avoid unnecessary; MESOS-4838 will
enhance it to trigger allocate in batch.

> Currently, if "/machine/schedule" did not include the {{DOWN}} machine, the request will
be rejected; it's inconvenient for operator to collect all {{DOWN}} machines and add it into
scheduler request. The proposal solution is to ignore {{DOWN}} machines in "/machine/schedule".
