Hello,
Often when I connect hdfs with these parameters :
I can connect, but often the connection fails, returning this error :
IS RANDOM…
Can anyone help me understand?
I use knime 4.6.0
Hi @And,
I guess your principal contains invalid characters or characters that do not work with rules to map them. See auth_to_local in the Hadoop config or MIT Kerberos.
Are you using random or frequently changing principals?
Cheers,
Sascha
