----------------------------------------
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/[email protected]",
command-179.json:
"dfs.journalnode.kerberos.internal.spnego.principal": "HTTP/[email protected]",
command-184.json:
"dfs.journalnode.kerberos.internal.spnego.principal": "HTTP/[email protected]",
{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
