----------------------------------------

             Summary: JournalNode kerberos configs are missing when trying to enable HA
                 Key: AMBARI-9832
                 URL: https://issues.apache.org/jira/browse/AMBARI-9832
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.0.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
            Priority: Critical
             Fix For: 2.0.0


1. build a two node cluster, with 1 ZK (everything on c6401). c6402 should only have DN, NM and clients
2. Then add a host c6403 with just DN, NM and clients
3. Then add two ZKs (to c6402 and c6403)
4. Then enable kerb.
5. Then try to enable namenode HA.

Result:
JournalNodes start fails.

During enabling HA journalnode "kerberos configs" were added to hdfs-site.xml:
{noformat}
[root@c6401 data]# grep -ri "dfs.journalnode.kerberos.internal.spnego.principal" *
command-175.json:            "dfs.journalnode.kerberos.internal.spnego.principal": "HTTP/_HOST@EXAMPLE.COM", 
command-179.json:            "dfs.journalnode.kerberos.internal.spnego.principal": "HTTP/_HOST@EXAMPLE.COM", 
command-184.json:            "dfs.journalnode.kerberos.internal.spnego.principal": "HTTP/_HOST@EXAMPLE.COM",
{noformat}
But when JNs were stating those configurations have not been in hdfs-site.xml and command.json.
{noformat}
[root@c6401 data]# grep -ri "dfs.journalnode.kerberos.internal.spnego.principal" command-188.json 
[root@c6401 data]# 
{noformat}

{code}
Exception in thread "main" java.io.IOException: Running in secure mode, but config doesn't have a keytab
        at org.apache.hadoop.security.SecurityUtil.login(SecurityUtil.java:236)
        at org.apache.hadoop.hdfs.qjournal.server.JournalNode.start(JournalNode.java:144)

{code}

*I could not reproduce it at the second attempt*
