> URL: https://issues.apache.org/jira/browse/NIFI-6124
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Hari Sekhon
> Priority: Major
>
> NiFi HDFS processors appear to be resolving the host component of the
> kerberos principal given an hdfs-site.xml using the usual Hadoop _HOST
> placeholder like so:
> {code:java}
> <property>
> <name>dfs.namenode.kerberos.principal</name>
> <value>hdfs/_HOST@<domain></value>
> </property>{code}
> Results in an exception like this:
> {code:java}
> 2019-03-15 09:55:42,556 INFO [Timer-Driven Process Thread-6]
> o.a.h.io.retry.RetryInvocationHandler java.io.IOException: Failed on local
> exception: java.io.IOException: Couldn't set up IO streams:
> java.lang.IllegalArgumentException: Server has invalid Kerberos principal:
> hdfs/<fqdn>@<domain>, expecting: hdfs/<ip_x.x.x.x>@<domain>; Host Details :
> local host is: "<fqdn>/<ip_x.x.x.x>"; destination host is:
> "<ip_x.x.x.x>":8020; , while invoking
> ClientNamenodeProtocolTranslatorPB.getFileInfo over
> <ip_x.x.x.x>/<ip_x.x.x.x>:8020 after 9 failover attempts. Trying to failover
> after sleeping for 17661ms.
