--------------------------------------
Summary: Run HA secure tests from s3g container
Key: HDDS-8219
URL: https://issues.apache.org/jira/browse/HDDS-8219
Project: Apache Ozone
Issue Type: Sub-task
Components: test
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
In {{ozonesecure-ha}} environment SCM containers have hostnames like
"scm1.org", but all Kerberos principals for SCM nodes are in the form
{{testuser/[email protected]}}. Since no host named {{scm}} exists, lookup
takes quite some time:
{code}
$ OZONE_LOGLEVEL=TRACE ozone sh volume create /vol1 |& grep 'lookup'
[main] TRACE security.SecurityUtil: Name lookup for om2 took 1 ms.
[main] TRACE security.SecurityUtil: Name lookup for om3 took 0 ms.
[main] TRACE security.SecurityUtil: Name lookup for om1 took 0 ms.
[main] TRACE security.SecurityUtil: Name lookup for scm took 497 ms.
{code}
We can improve this simply by executing the same commands from another
container, e.g. {{s3g}}:
{code}
$ OZONE_LOGLEVEL=TRACE ozone sh volume create /vol2 |& grep 'lookup'
[main] TRACE security.SecurityUtil: Name lookup for om2 took 1 ms.
[main] TRACE security.SecurityUtil: Name lookup for om3 took 0 ms.
[main] TRACE security.SecurityUtil: Name lookup for om1 took 0 ms.
[main] TRACE security.SecurityUtil: Name lookup for s3g took 0 ms.
{code}
