Hi,

I am using the webhdfs plugin of Logstash to send files to HDFS host system which uses the Kerberos authentication. After the config I see errors while the Logstash startup.

Any suggestions about this issue?

**Webhdfs conf**

webhdfs {  
host =\> "[ylpd1665.kmdc.att.com](http://ylpd1665.kmdc.att.com)" # (required)  
port =\> 50070 # (optional, default: 50070)  
standby\_host =\> "[ylpd1667.kmdc.att.com](http://ylpd1667.kmdc.att.com)"  
standby\_port =\> 50070  
user =\> "user"  
path =\> "tmp/events-%{[@timestamp]}.log"  
compression =\> "none"  
codec =\> "json"  
use\_kerberos\_auth =\> true  
kerberos\_keytab =\> "/home/user/user.keytab"  
}

**Error**
