I should mention that I have also tried to access fileSize like this
without success:
//def file_size = (ff.size != null) ? (ff.size as Integer) : 0
def file_size = ff.getAttribute('fileSize')
This returns null.
I tried this approach based on a post in cloudera, which said this:
|The default FlowFile attributes include:
entryDate
lineageStartDate
fileSize
filename
path
uuid
