Hi Michael, Thanks for your reply. Please find the attached global.json files. global.json - we have pointed to active namenode. It's working fine, global_with_HA_name - We used namenode HA name to access the HDFS location, and it throws an exception, details are added in my previous mail. global_with_http - we used HTTP to access the jar file, we are not getting an error, but the functions are not loading.
