NiFi PutFile manipulate lastModifiedTime

NiFi PutFile manipulate lastModifiedTime

New Contributor

Hi all, i need some help with this behaviour. I have 2 processors (GetFTP > PutFTP) and i had a trouble with the manipulation about the lastModifiedTime, i need to set the original date of the sourcefile when i do the PutFTP .

i had let the property unset but the attribute lastModifiedTime has change.

Nifi version 1.4.0-rc2

The documentation saids:

45672-putftp-conf.png

The lastModifiedTime to assign to the file after transferring it. If not set, the lastModifiedTime will not be changed. Format must be yyyy-MM-dd'T'HH:mm:ssZ. You may also use expression language such as ${file.lastModifiedTime}. If the value is invalid, the processor will not be invalid but will fail to change lastModifiedTime of the file.
Supports Expression Language: true

Scenario 1:-

In your PutFTP processor change

Last Modified Time property to

${file.lastModifiedTime}

If we mention the property value as above in putftp processor configurations then the new file(push test directory) will have same lastmodifiedtime as the sourcefile.

Configs:-

Scenario 2:-

If we keep the Last Modified Time property as Blank(same configurations as mentioned in your question)

Then putftp processor will set last modified time of the file as new time(not the source file last modified time).

When we pulls the file from the Destination directory(push test) we are going to see the Different last modified times compared to source file(pull test) last modified time.

I think you are facing scenario 2 to get same last modified time as source file just change the property as suggested above in Scenario 1.

Then compare the Last Modified Times between source file(pull test) with destination file(push test), they are going to be same.

Hi Shu, thanks for your answer.

i had tried your advice setting the ${file.lastModifiedTime} but the processor raise this warning and set the execution date as the lastModifiedTime on the destination file .

Hi @Shu

After read this warning and review in detail the code of the PutFile Processor, i had find line 394:

// FTP server probably doesn't support MFMT command

So i guess that this behaviour its related with the vsftpd server (version 3.0.3). I will test another ftpserver.
