Description

Tasks stuck in PENDING state due to unsatisfied host constraint don't have the reason set in TaskEvent.message. This makes the troubleshooting harder as neither UI nor aurora status can give any clues:

INFO] role: mesos, env: test, name: monitoring, shard: 147, status: PENDING on None
cpus: 0.5, ram: 512 MB, disk: 3072 MB
	failure count: 0 (max 1)
	events:
		 2014-05-02 09:05:43 PENDING: None
	metadata:
		package: mesos/monitoring v14
