Bruce Merry created MESOS-7197:
----------------------------------
Summary: Requesting tiny amount of CPU crashes master
Key: MESOS-7197
URL: https://issues.apache.org/jira/browse/MESOS-7197
Project: Mesos
Issue Type: Bug
Components: allocation
Affects Versions: 1.1.0
Environment: Ubuntu 14.04, using Mesosphere PPA to install Mesos
Reporter: Bruce Merry
Priority: Critical
If a task is submitted with a tiny CPU request e.g. 0.0004, then when it
completes the master crashes due to a CHECK failure:
{noformat}
F0302 10:48:26.654909 15391 sorter.cpp:291] Check failed:
allocations[name].resources[slaveId].contains(resources)
{noformat}
I can reproduce this with the following command:
{noformat}
mesos-execute --command='sleep 5' --master=$MASTER --name=crashtest
--resources='cpus:0.0004;mem:128'
{noformat}
If I replace 0.0004 with 0.001 the issue no longer occurs.
