Description

The DeleteHDFS processor does not wrap the usage of FileSystem in a doAs the way all the other HDFS processors do...

https://github.com/apache/nifi/blob/main/nifi-nar-bundles/nifi-hadoop-bundle/nifi-hdfs-processors/src/main/java/org/apache/nifi/processors/hadoop/DeleteHDFS.java#L148

 

Example from ListHDFS:

https://github.com/apache/nifi/blob/main/nifi-nar-bundles/nifi-hadoop-bundle/nifi-hdfs-processors/src/main/java/org/apache/nifi/processors/hadoop/ListHDFS.java#L570-L572

It is important to call getUgi() first which is where the relogin/error handling is.
