[jira] [Updated] (HADOOP-13322) Comment in Kerberos file is not
properly parsed
[ https://issues.apache.org/jira/browse/HADOOP-13322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Serhiy Boychenko updated HADOOP-13322:
--------------------------------------
Description:
Hello,
I am receiving an error when trying to authenticate with Kerberos:
Exception in thread "main" java.lang.IllegalArgumentException: Can't get Kerberos realm
at org.apache.hadoop.security.HadoopKerberosName.setConfiguration(HadoopKerberosName.java:65)

... 9 more
The krb5.conf file, somewhere in the middle has a comment starting with semicolumn ( ; ) and it crashes the code. I have tried with the hash and it seems to be working properly. The krb5.conf file has semicolumn-started comments in the beginning and those are getting parsed correctly, what is breaking the code in the semicolumn in the middle of the configuration. The file looks like:
; Some comment.
[libdefaults]
default_realm = EXAMPLE.COM
...
; comment
[realms]
EXAMPLE.ORG = {
...
}
I have been looking into the Web to understand if both characters can be used as comments and it seems they can according to the following resource:

Thank you,
Serhiy.
