java - Kerberos Authentication Error - When loading Hadoop Config Files from SharedPath -

i developing java application , application saving result data hdfs. java application should run in windows machine.

we using kerberos authentication , placed keytab file in nas drive. , saved hadoop config files in same nas drive.

my issues when load hadoop config files nas drive, throwing me authetication error, application running fine if load config files local file system (i saved config files inside c:\hadoop)

below working code snippet. (keytab file in nas, hadoop config files in local file system)

static string keytabpath = "\\\\path\\2\\keytabfile\\name.keytab" configuration config = new configuration();         config.set("fs.defaultfs", "hdfs://xxx.xx.xx.com:8020");         config.addresource(new path("c:\\hadoop\\core-site.xml"));         config.addresource(new path("c:\\hadoop\\hdfs-site.xml"));         config.addresource(new path("c:\\hadoop\\mapred-site.xml"));         config.addresource(new path("c:\\hadoop\\yarn-site.xml"));         config.set("fs.hdfs.impl", org.apache.hadoop.hdfs.distributedfilesystem.class.getname());         config.set("fs.file.impl",org.apache.hadoop.fs.localfilesystem.class.getname());         // kerberos authentication         config.set("hadoop.security.authentication", "kerberos");         usergroupinformation.setconfiguration(config);         usergroupinformation.loginuserfromkeytab("name@xx.xx.com",keytabpath); 

i tried loading config files nas drive getting kerberos authentication error. below code snippet throwing error (keytab file in nas , hadoop config files in nas)

static string keytabpath = "\\\\path\\2\\keytabfile\\name.keytab" configuration config = new configuration();         config.set("fs.defaultfs", "hdfs://xxx.xx.xx.com:8020");         config.addresource(new path("\\\\nasdrive\\core-site.xml"));         config.addresource(new path("\\\\nasdrive\\hdfs-site.xml"));         config.addresource(new path("\\\\nasdrive\\mapred-site.xml"));         config.addresource(new path("\\\\nasdrive\\yarn-site.xml"));         config.set("fs.hdfs.impl", org.apache.hadoop.hdfs.distributedfilesystem.class.getname());         config.set("fs.file.impl",org.apache.hadoop.fs.localfilesystem.class.getname());         // kerberos authentication         config.set("hadoop.security.authentication", "kerberos");         usergroupinformation.setconfiguration(config);         usergroupinformation.loginuserfromkeytab("name@xx.xx.com",keytabpath); 

below error message
