Connor Doyle created MESOS-1892:
-----------------------------------
Summary: Using mesos-0.20.1.jar with libmesos-0.21.0 reliably
segfaults
Key: MESOS-1892
URL: https://issues.apache.org/jira/browse/MESOS-1892
Project: Mesos
Issue Type: Bug
Components: java api
Affects Versions: 0.21.0
Environment: Observed on Ubuntu 14.04.1 LTS (trusty).
Reporter: Connor Doyle
Assignee: Timothy Chen
Priority: Critical
The segfault seems to occur on every call to driver.launchTasks()
Here is a minimal(ish) Java framework for testing purposes:
https://github.com/ConnorDoyle/mesos-compat
Here is some output from running the framework against a Mesos 0.20.1 cluster
with libmesos-0.20.1:
