             Summary: SCM HA performance degradation upon one peer down.
                 Key: HDDS-5703
                 URL: https://issues.apache.org/jira/browse/HDDS-5703
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Mark Gui


When we use the SCM benchmark tool (https://issues.apache.org/jira/browse/HDDS-5702) to test SCM throughput for AllocateContainer, we found a dramatic degradation in the throughput when one scm peer(follower) is down.

Here is some statistics.

Normal Case:

 
{code:java}
***************************************
Total allocated containers: 500000
Total failed containers: 0
Execution Time: 02:36:50,151
Throughput: 53.000000 (ops)
***************************************
{code}
One scm follower down:

 

 
{code:java}
***************************************
Total allocated containers: 50000
Total failed containers: 0
Execution Time: 02:22:00,245
Throughput: 5.000000 (ops)
***************************************
{code}
The overall throughput drops to 1/10 of the original.
