As far as I know, the <CODE>PutFile</CODE> processor cannot append to an existing file. You are given the option to deal with conflicting files using "replace", "ignore", or "fail" as a resolution strategy. You should submit an Apache Jira to add this functionality. I could see difficulties with file locks and flushing the buffer given the streaming nature of NiFi and I think further investigation is needed. </P> Sat, 29 Oct 2016 10:50:32 GMT alopresto 2016-10-29T10:50:32Z https://community.cloudera.com/t5/Archives-of-Support-Questions/In-NiFi-how-do-I-append-RouteText-lines-to-an-existing/m-p/153513#M44732 <P>I have a RouteText processor outputting matched lines that I would like to append to an existing local file using PutFile. However, PutFile cannot append content to an existing file (am I wrong?). How do I do this in NiFi? Is the only way to do it by using a script in ExecuteScript to open and append a file? Seems like a native Processor should do this.</P> Fri, 28 Oct 2016 02:38:25 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/In-NiFi-how-do-I-append-RouteText-lines-to-an-existing/m-p/153513#M44732 gkeys 2016-10-28T02:38:25Z https://community.cloudera.com/t5/Archives-of-Support-Questions/In-NiFi-how-do-I-append-RouteText-lines-to-an-existing/m-p/153514#M44733 <P> <A rel="user" href="https://community.cloudera.com/users/11288/gkeys.html" nodeid="11288">@Greg Keys</A> unfortunately I think you are correct that <CODE>ExecuteScript</CODE> is the best way to achieve this right now.
