Kunal Thakar commented on MESOS-6596:
-------------------------------------
The master is running version 1.0.0-rc3 and the agent is running 1.0.1
The /master/state-summary endpoint shows that resources are available, and yet
the /reserve call fails (and then eventually succeeds)
Pasting the body of the request:
{code}
curl -v -i -u <u>:<auth> -d slaveId=e6e07ff7-d0ff-4f57-a2b3-5e1929635a3f-S1633
-d 'resources=[

},

}
]' -X POST http://<master>:5050/master/reserve
{code}
If it is a validation failure, it should always fail, but that doesn't seem to
be the case here.

> The operation to dynamically reserve a host for a framework consistently

> We are calling the /reserve endpoint on the master with the same payload and
> it mostly returns 409, with the occasional success. Pasting the output of two
