> Key: AMBARI-14847
> URL: https://issues.apache.org/jira/browse/AMBARI-14847
> Project: Ambari
> Issue Type: Bug
> Components: ambari-agent
> Affects Versions: 2.0.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.2.2
>
> Attachments: AMBARI-14847.patch
>
>
> The alerts framework on each Ambari Agent runs alerts in a threadpool when
> the job triggers. This can cause the following error to randomly appear and
> the alert to go CRITICAL:
> {noformat}
> Connection failed to http://nat-rare-21-dvitiiuk-2-5.novalocal:8088
> (Execution of '/usr/bin/kinit -l 5m -c
> /var/lib/ambari-agent/tmp/web_alert_cc_f3f99363c3b7d1667f1287ce3a35aa52 -kt
> /etc/security/keytabs/spnego.service.keytab
> HTTP/[email protected] > /dev/null' returned 1.
> kinit: Internal credentials cache error while storing credentials while
> getting initial credentials)
> {noformat}
> The alerts would randomly go CRITICAL at the end of their ticket expiration
> time only to become OK again shortly after.
> The cause is that the {{kinit}} command being executed to create new
> credentials cannot be run concurrently for the same user.
