Hi guys,

I installed ozone 0.5 (with CDP but i don't think it changed anything) and
I enabled kerberos. The setup has 4 datanodes with a single rack.
When I ingest data in a specific bucket using the HadoopFS with Nifi, I can
see that all the containers get always created on the 3 same datanodes.
Is there any reason why the last datanode don't get any container? Is it an
expected behavior and how can I troubleshoot that? I didn't see anything in
the log that can give me a hint.

I tried to stop one of the datanode having containers to see if the
containers will get created on the datanode number4 but nothing happened. I
restarted the OM/SCM and the 3 datanodes still up and then it started to
replicate the containers because there was a missing replica.

After bringing back the datanode that I shutdown at the beginning, I
restart the ingestion of data and again the new container gets created only
3 specific datanode.

If you have any tips or explanations that will be helpful.

Thanks,
Michel
