             Summary: Ambari agent repository checking causing rpmdb corruption
                 Key: AMBARI-25509
                 URL: https://issues.apache.org/jira/browse/AMBARI-25509
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: 2.7.3
         Environment: Running RHEL7, Ambari and agent running as root in Centrify-managed environment. Ambari part of Hortonworks (now Cloudera) HDF (NiFi) 3.4.1.1.  Using Ambari 2.7.3. Outside of Ambari, when running as root, the call to check yum repos takes 20 minutes or more. In our circumstance running repo check as root locks the rpmdb.

Ambari-agent runs its repo check and eventually kill -9's the task, corrupting our rpmdb.   Side effect - now yum-cron is getting hung up since it can't access the repo either and we start having lots of yum-repo cron checking processes hanging in the OS. Our nightly netbackup file backups are also failing.

Happening in four different clusters on almost all 39 servers since late January. These environments have lots of service restarts.   
            Reporter: Mike Woodcock


Exactly the same issue as https://issues.apache.org/jira/browse/AMBARI-6702.  Slightly different circumstances.  Using Ambari 2.7.3.  Outside of Ambari, when running as root, the call to check yum repos takes 20 minutes or more. In our circumstance, running repo check as root locks the rpmdb.  When Amabari-agent runs its repo check and sends kill -9, since it cannot wait 20 minutes, our repodb becomes corrupted.
