BDR jobs run on 1 server

BDR jobs run on 1 server

Explorer

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 fix for this was to upgrade CM from 5.8.3 to 5.14.3

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
