      Description

      If Kerberos credential cache file location is overridden in environment, then KDiag tries to read its value for Kerberos configuration. For example,

      # 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 = '�'
      

      Expected Behavior:
      1. Kerberos configuration file location should be read from KRB5_CONFIG env. variable instead of KRB5CCNAME. Source: MIT KRB5 doc
