> 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.
