Aurora Instances are always pending status after submitted Heron Topology
I was deployed a Twitter Heron cluster with Aurora and Mesos. The components of the cluster as following list:
- Scheduler: Aurora scheduler
- State Manager: zookeeper
- Uploader: HDFS
The instances of Aurora are always pending status after I submitted the example topology named WordCountTopology. The following is a screenshot of the cluster running.
Mesos agents:
Aurora scheduler:
Where is the problem? Is the machine's resources in the cluster can not meet the needs the tasks of togology? Thanks for your help.
Solution

481 and 485mb doesn’t seem to be enough.
