I want to remove session in case i get certain data from file i have code
like this,but i got errors "flowfile has already marked for removal", what
should i change to get rid of extra errors?
In case of session rollback flowfile will dissapear in queues also?
2.should i use rollback instead of remove()?
NodeList childNodes = nodeGettingChanged.getChildNodes();for(int i =0; i !=
childNodes.getLength();++i)
{Node child = childNodes.item(i);if(!(child
instanceofElement))continue;if(child.getNodeName().equals("runAs")){if(child.getFirstChild().getTextContent()=="false"){
session.remove(flowFile1);File
deleteExtraFile
=newFile("C://Users//s.tkhilaishvili//Desktop//try2//nifi-1.3.0//1//conf.xml");booleandelete=deleteExtraFile.delete();}else{
child.getFirstChild().setNodeValue("false");}}}
Document finalXmlDocument = xmlDocument; session.write(flowFile1, new
StreamCallback() {
publicvoid process(InputStream inputStream,OutputStream
outputStream)throwsIOException{TransformerFactory transformerFactory
=TransformerFactory.newInstance();Transformer transformer =null;try{
transformer =
transformerFactory.newTransformer();}catch(TransformerConfigurationException
e){
e.printStackTrace();}DOMSource source
=newDOMSource(finalXmlDocument);
ffStream.close();ByteArrayOutputStream bos
=newByteArrayOutputStream();StreamResult result =newStreamResult(bos);try{
transformer.transform(source,
result);}catch(TransformerException e){
e.printStackTrace();}byte[] array =
bos.toByteArray();
outputStream.write(array);}});
session.remove(flowFile);
session.transfer(flowFile1, REL_SUCCESS);}
