I configured a pipeline using the webhdfs output plugin, but i'm having trouble to login into kerberos using a keytab.
If i login by command line using the keytab "kinit -kt <keytab_file> " , i get the kerberos ticket and the pipeline works perfectly however if i destroy the kerberos ticket and i run the pipeline, the plugin is not able to login using the keytab.
Do you know if there's a bug with this plugin?.. or maybe the problem is the GSSAPI gem that is using to login into kerberos?
