Zhitao Li created MESOS-7566: -------------------------------- Summary: Master crash due to failed check in DRFSorter::remove Key: MESOS-7566 URL: https://issues.apache.org/jira/browse/MESOS-7566 Project: Mesos Issue Type: Bug Affects Versions: 1.1.1, 1.1.2 Reporter: Zhitao Li Priority: Critical
A check in [https://github.com/apache/mesos/blob/1.1.2/src/master/allocator/sorter/drf/sorter.cpp#L355 DRFSorter] is triggered occasionally in our cluster and crashes the master leader. I manually modified that check to print out the related variables, and the following is a master log. https://gist.github.com/zhitaoli/0662d9fe1f6d57de344951c05b536bad#file-gistfile1-txt >From the log, it seems like the check was using an stale value of >{{cpus(*){REV}:26}} while the new value was updated to {{cpus(*){REV}:25}}, >thus it crashed. So far two verified occurrence of this bug are both observed near an {{UNRESERVE}} operation (see lines above in the log). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
