BDR jobs run on 1 server

[#1]

I have 34 hosts in my cluster. I have several BDR jobs and they all run on the same host. Shouldn't they be running on different hosts? What determines which host a job runs on?

The BDR should run on different hosts, does your CM Server version match our release notes [0]

Only use healthy HDFS/Hive hosts for launching replication jobs

BDR Replication Host Selection Policy has been updated. The process that launches and coordinates a HDFS/Hive replication job will now only run on the following hosts:

• Hosts that run any role of the HDFS/Hive Service (for HDFS or Hive replication)
• Hosts that have a Non-Gateway role
• Hosts where the health status is in the GOOD or CONCERNING state with preference given to GOOD
• Hosts that are whitelisted, if configured

The fix for this was to upgrade CM from 5.8.3 to 5.14.3
