I'm seeing this too:

(mesos-cli)[benh@tw-mbp13-bhindman ~]$ mesos ps
===>You have no tasks for that filter<===
(mesos-cli)[benh@tw-mbp13-bhindman ~]$ mesos ps -i

Hmmm, I need a debug command that saves the responses. In the mean time, I'll get that protected so that it doesn't explode.

[Stephan Erb]

If I remember correctly, you get this when a task has not reached the RUNNING state, yet.

[Thomas Rampelberg]

@StephanErb I bet you're exactly right, I just recently made tasks not in running yet get included in that list (speeds up time to tail). Thanks!
