---------------------------------------------
Summary: PutFile fails if filename property includes a path
Key: MINIFICPP-286
URL: https://issues.apache.org/jira/browse/MINIFICPP-286
Project: NiFi MiNiFi C++
Issue Type: Bug
Reporter: Andrew Christianson
Assignee: Andrew Christianson
Priority: Major
If a flowfile 'filename' property includes a path (i.e. nested subdirs), then
PutFile fails due to improper creation of temporary write file.
Example ExecuteScript lua to update filename:
{code}
function onTrigger(context, session)
flow_file = session:get()
log:info('rename_file triggered')
if flow_file ~= nil then
file_name = flow_file:getAttribute('filename')
new_file_name = 'a/b/' .. file_name
log:info('renaming ' .. flow_file:getAttribute('filename') .. ' to ' ..
new_file_name)
flow_file:updateAttribute('filename', new_file_name)
session:transfer(flow_file, REL_SUCCESS)
log:info('rename_file success')
else
log:info('no work to do')
end
end
{code}
Log output showing the error:
{code}
