Signed-off-by: Joe Witt <[email protected]>
> PutHDFS silently ignores exceptions when closing temporary file output stream

> The PutHDFS processor can silently fail when closing an output stream when
> it's finished writing FlowFiles to a temporary space in HDFS.
> {{DFSOutputStream}} can throw an {{IOException}} when it's closed and that's
> ignored by the processor. This results in the FlowFile getting dropped (e.g.
> a loss of data) when it should be routed to the failure relationship.
> Source:
> [https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-hadoop-bundle/nifi-hdfs-processors/src/main/java/org/apache/nifi/processors/hadoop/PutHDFS.java#L365]
> Instead, the exception should be caught & thrown and the FlowFile should be
> routed to the failure relationship. There's probably an argument to avoid
> ignoring _any_ exception.
