Hello,

The behavior you're seeing is due to a bug we've addressed in 2017_01_21. To properly start the cluster:

  • shut down datafusion-admin, df-services, and extera
  • Once extera has stopped, look for and kill any remaining Java processes:
    • e.g. - ps aux | grep -i java
    • e.g. - kill -9 <pid>
  • Once all processes have been killed, restart extera, df-services, and datafusion-admin in that order.

Thanks,

Jeff
