Falcon feed throwing an error during feed schedule ERROR: Bad Request;default/E0803 : E0803: IO error, null

Guru

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

ERROR: Bad Request;default/E0803 : E0803: IO error, null

CausedBy: E0803: IO error, null

Following is falcon logs error.

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
