> GetHDFSSequenceFile sequence reader throwing away authenticated filesystem

> 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
