Meng Zhu reassigned MESOS-9786: ------------------------------- Assignee: Meng Zhu > Race between two REMOVE_QUOTA calls crashes the master. > ------------------------------------------------------- > > Key: MESOS-9786 > URL: https://issues.apache.org/jira/browse/MESOS-9786 > Project: Mesos > Issue Type: Bug > Affects Versions: 1.5.1, 1.8.0, 1.8.1 > Reporter: Andrei Sekretenko > Assignee: Meng Zhu > Priority: Major > Labels: resource-management > > The existence of the quota in the master is validated here: > [https://github.com/apache/mesos/blob/a9a2acabd03181865055b77cf81e7bb310b236d6/src/master/quota_handler.cpp#L700] > Then the quota is removed from master in a deferred method call: > [https://github.com/apache/mesos/blob/a9a2acabd03181865055b77cf81e7bb310b236d6/src/master/quota_handler.cpp#L744] > And then removed from allocator in another deferred call: > [https://github.com/apache/mesos/blob/a9a2acabd03181865055b77cf81e7bb310b236d6/src/master/quota_handler.cpp#L753] > So, there is a race between two simultaneous REMOVE_QUOTA calls. > We observe this race on a heavily loaded cluster. Currently we suspect that > the client retries the call (due to the call being not processed for a long > time), and this triggers the race. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
