Failed to retrieve connection info for urlid inputfile Cause please set up authentication file home hduser sqltool rc

Question

i am trying to run a jar file in terminal.However when i do that i get the error

Failed to retrieve connection info for urlid "inputfile".Cause :please set up authentication file '/home/hduser/sqltool.rc'

The weird thing is i am not using sql at all neither in hadoop nor in my jar file.My command in the terminal is as follows:

hduser@tasneem-Aspire-A515-51G:/usr/local/hadoop-3.3.0$ hadoop jar DataAnalytics.jar inputfile data.json

DataAnalytics.jar is my jar file and the main class is called inputfile.The data.json file has the input and output path for the mapreduce job.

hadoop-version:  hadoop-3.3.0

java version :  openjdk1.8

OS:  ubuntu 16.04
