----------------------------------
Summary: Kerberos support for Hadoop processors
Key: NIFI-866
URL: https://issues.apache.org/jira/browse/NIFI-866
Project: Apache NiFi
Issue Type: New Feature
Reporter: Ricky Saltzer
Assignee: Ricky Saltzer
Currently the AbstractHadoopProcessor only supports talking to non-kerberos
Hadoop clusters. Even though the user might be supplying a Hadoop configuration
which indicates the authentication implementation is Kerberos, NiFi will still
attempt to connect via SIMPLE authentication. This results in a processor
exception.
*Goals:*
* Minimal configuration for Kerberos support
* Shouldn't have to configure individual processors (e.g. user could have tens
to hundreds of these processors)
*Non-Goals:*
* Support more than one kerberos principal at a time
* Support both secure and non-secure connections at the same time
*Basic Usage Proposal:*
Edit _conf/nifi.properties_ and modify the following values
{code:title=nifi.properties|borderStyle=solid}
..
# kerberos #
nifi.kerberos.enabled=true
nifi.kerberos.krb5.file=/path/to/krb5.conf
nifi.kerberos.keytab=/path/to/user.keytab
nifi.kerberos.principal=user@REALM
{code}
