I am trying schedule falcon feed and getting following error.

Note: It is giving an error after I tried to run falcon cluster on NN HA. and it was running fine if I do not make Namenode HA in falcon cluster.

falcon entity -type feed -name replicationFeed2 -schedule

Did you configure Falcon for HA according to these instructions?

There was a missing configuration in source cluster in oozie service.

oozie.service.HadoopAccessorService.hadoop.configurations=*={{hadoop_conf_dir}},m1.hdp22:8050=/hdptmp/testconfig,m2.hdp22:8050=/hdptmp/testconfig,m1.hdp22:8020=/hdptmp/testconfig,m2.hdp22:8020=/hdptmp/testconfig
