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:

  1. Scheduler: Aurora scheduler
  2. State Manager: zookeeper
  3. 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:

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

  • Well, the message in the lower screen has a clear indication that you assigned not enough memory to the agents.

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