Subject [jira] [Updated] (HADOOP-15123) KDiag tries to load krb5.conf from KRB5CCNAME instead of KRB5_CONFIG
Date Sat, 16 Dec 2017 05:03:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15123?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vipin Rathor updated HADOOP-15123:
----------------------------------
    Description: 
If Kerberos credential cache file location is overridden in environment, then KDiag tries
to read its value for Kerberos configuration. For example,

{code:java}
# export KRB5CCNAME=/tmp/krb5cc_1001
# hadoop org.apache.hadoop.security.KDiag
...
...
== Locating Kerberos configuration file ==

Setting kerberos path from environment variable KRB5CCNAME: "/tmp/krb5cc_1001"
Kerberos configuration file = /tmp/krb5cc_1001
17/12/16 04:06:19 ERROR security.KDiag: java.util.UnknownFormatConversionException: Conversion
= '�'
java.util.UnknownFormatConversionException: Conversion = '�'
{code}

Expected Behavior:
1. Kerberos configuration file location should be read from KRB5_CONFIG env. variable instead
of KRB5CCNAME. Source: [MIT KRB5 doc|https://web.mit.edu/kerberos/krb5-1.12/doc/admin/conf_files/krb5_conf.html]
