In 0.8.2 We create an app, marathon return success. But it never really create it. And it not in deployment nor in queue.
So we upgrade to 0.9.2
It shows error:
Could not modify Group with key: root:2015-07-31T08:50:18.342Z
We remove some zookeeper log/snapshot. It is ok.
But after we recover some apps, the error appear again.
