----------------------------------
Summary: Improvements for PutHDFS attribute handling
Key: NIFI-1929
URL: https://issues.apache.org/jira/browse/NIFI-1929
Project: Apache NiFi
Issue Type: Improvement
Reporter: Matt Burgess
The following is a list of improvements/fixes to attribute handling in PutHDFS
for consideration:
1) The documentation says that PutHDFS writes the "filename" attribute with the
description: "The name of the file written to HDFS comes from the value of this
attribute." PutHDFS should add a @ReadsAttribute annotation with the above
description.
2) The @WritesAttribute description above should read something like: The name
of the file written to HDFS is stored in this attribute." Also it doesn't
appear by the code that this is accurate; the filename could've changed
depending on the compression option, but it appears the original filename
attribute value is retained
3) PutHDFS should write an attribute (such as absolute.path like GetFile) that
contains the value of the Directory property after any Expression Language has
been evaluated. This would be documented via @WritesAttribute.
#2 and #3 are being done for the Transit URI in the reported provenance
event(s), this should be extended to the flow file attributes as well.
