syam prasad commented on KAFKA-4097:
------------------------------------
I was able to identify the root cause for this issue. the SPN for zookeeper was
not constructed in a correct way. This can be seen by enabling kerberos logs
(-Dsun.security.krb5.debug=true). As NSLOOKUP command returns correct hostname
in FQDN format, I have never suspected /etc/hosts file. But there is some
problem with /etc/hosts file.
The conventional format of hosts file should be some thing like below:
< IP > <FQDN> <ShortName>
Example:
9.124.101.5 archimedes.in.ibm.com archimedes
But in my hosts file, shortname precedes FQDN. Hence the issue.
Thanks for your time.
