https://community.cloudera.com/t5/Support-Questions/Listing-S3-Bucket-files-using-python-in-NiFi-ExecuteScript/m-p/231803#M193646 <P>Hi, Since we can mention only one prefix in ListS3 processor I am trying to access AWS S3 using Python boto3 in NiFi ExecuteScript processor. If this succeeds, I can send a list of folder paths to the python script to get files from various folders under S3 bucket. I provided the path of boto3-1.6.0.tar.gz in ModuleDirectory but I get the below error. </P><P><A rel="user" href="https://community.cloudera.com/users/641/mburgess.html" nodeid="641" target="_blank">@Matt Burgess </A><A rel="user" href="https://community.cloudera.com/users/363/bbende.html" nodeid="363" target="_blank">@Bryan Bende</A> <A rel="user" href="https://community.cloudera.com/users/536/mfoley.html" nodeid="536" target="_blank">@Matt Foley</A> Please let me know how to fix this and achieve use case. </P><P>ExecuteScript Processor :</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="64411-executescript-python-s3.jpg" style="width: 804px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/14910i719607EC9C8E64A5/image-size/medium?v=v2&amp;px=400" role="button" title="64411-executescript-python-s3.jpg" alt="64411-executescript-python-s3.jpg" /></span></P><P>Error:</P><PRE>ExecuteScript[id=d6cf51e8-0161-1000-32de-7748af781842] Failed to process session due to org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: ImportError: No module named boto3 in &lt;script&gt; at line number 1: javax.script.ScriptException: ImportError: No module named boto3 in &lt;script&gt; at line number 1</PRE> Sun, 18 Aug 2019 00:34:04 GMT vinaychandra_t 2019-08-18T00:34:04Z
