title: Split Nifi Attribute Value To Multiple Attributes
body: <p>I have a file which i get using the GetFile Processor.</p>
  
  <p>The flowfile generated from this has an attribute (filename).</p>
  
  <p>I want to split this "filename" attribute with value "ABC_gh_1245_ty.csv" by "_" into multiple attributes</p>
  
  <pre><code>ATTR1 = "ABC"
  ATTR2 = "gh"
  ATTR3 = "1245"
  ATTR4 = "ty.csv"
  </code></pre>
  
  <p>I presume that there are no processors available for this functionality in nifi 1.7.1</p>
  
  <p>I googled and found this custom processor:
  <a href="https://github.com/guvencenanguvenal/nifi-splitcreateattribute" rel="nofollow noreferrer">https://github.com/guvencenanguvenal/nifi-splitcreateattribute</a></p>
  
  <p>It still doesnt work. It errors out with 'Attribuite dont found'</p>
