Subject [jira] [Commented] (MESOS-4025) SlaveRecoveryTest/0.GCExecutor is flaky.
Date Fri, 11 Dec 2015 11:25:11 GMT

    [ https://issues.apache.org/jira/browse/MESOS-4025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15052635#comment-15052635
] 

Jan Schlicht commented on MESOS-4025:
-------------------------------------
