> 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}
