Based on this answer in the community</P> <P><A href="https://community.cloudera.com/t5/Community-Articles/How-to-Submit-Spark-Application-through-Livy-REST-API/ta-p/247502" target="_blank" rel="noopener">https://community.cloudera.com/t5/Community-Articles/How-to-Submit-Spark-Application-through-Livy-REST-API/ta-p/247502</A></P> <P>I created a test1.json as follows</P> <P>{<BR />"jars": ["hive-warehouse-connector-assembly-1.0.0.3.1.0.0-78.jar"],<BR />"pyFiles": ["pyspark_hwc-1.0.0.3.1.0.0-78.zip"],<BR />"files": ["test1.py"]<BR />}</P> <P>&nbsp;</P> <P>I use GetFile to get the json file and call InvokeHTTP to POST the request. I get the following error in HTTP Response</P> <DIV>This is HTTP response <DIV>invokehttp.response.body</DIV> <DIV>"requirement failed: File is required."</DIV> <DIV>&nbsp;</DIV> <DIV>I am not sure whether the field "files" should have the pyspark script or whether the pyspark script should be listed against 'pyFiles'. I tried this also but I get the same error. Please let me know what I am missing?</DIV> <DIV>&nbsp;</DIV> <DIV>Thanks</DIV> <DIV>Ganesh</DIV> </DIV> <P>&nbsp;</P> Fri, 10 Jan 2020 15:51:58 GMT TVGanesh 2020-01-10T15:51:58Z
