> Key: NIFI-2435
> URL: https://issues.apache.org/jira/browse/NIFI-2435
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.6.1
> Environment: Kerberos HDFS
> Reporter: Juan Sequeiros
> Assignee: Bryan Rosander
> Labels: hdfs, kerberos
>
> Hadoop Kerberos has a way of accessing things as an authenticated user
> UserGroupInformation.doAs
> NIFI is doing that to get access to the filesystem in order to basically tell hadoop to use the correct credentials so our processor does that correctly and then passes the results into the sequence reader unfortunately, the sequence reader then throws away our authenticated filesystem and creates its own without wrapping in a UGI.doAs
