Unable to validate location with path due to transcient failures when creating Cluster Apache Falcon

Unable to validate location with path /apps/falcon/primaryCluster/staging for cluster:primaryCluster due to transcient failures :

I have this error when i try to submit a cluster to Apache falcon. I believed it is due to permissions but I follow the step to switch the ownership to falcon user :

drwxr-xr-x - falcon hdfs 0 2016-02-10 10:17 /apps/falcon/backupCluster

drwxrwxrwx - falcon hdfs 0 2016-02-10 10:16 /apps/falcon/backupCluster/staging

drwxr-xr-x - falcon hdfs 0 2016-02-10 10:17 /apps/falcon/backupCluster/working

drwxr-xr-x - falcon hdfs 0 2016-02-10 10:16 /apps/falcon/primaryCluster

drwxrwxrwx - falcon hdfs 0 2016-02-10 10:16 /apps/falcon/primaryCluster/staging

drwxr-xr-x - falcon hdfs 0 2016-02-10 10:16 /apps/falcon/primaryCluster/working

Here is my xml :

<cluster xmlns='uri:falcon:cluster:0.1' name='primaryCluster' description='thie is primary cluster' colo='primaryColo'> <tags>primaryKey=primaryValue</tags> <interfaces> <interface type='readonly' endpoint='hftp://dl-master:50070' version='2.2.0'> </interface> <interface type='write' endpoint='hdfs://dl-master:8020' version='2.2.0'> </interface> <interface type='execute' endpoint='dl-master:8050' version='2.2.0'> </interface> <interface type='workflow' endpoint='http://dl-master:11000/oozie/' version='4.0.0'> </interface> <interface type='messaging' endpoint='tcp://10.0.0.5:61616?daemon=true' version='5.4.6'> </interface> </interfaces> <locations> <location name='staging' path='/apps/falcon/primaryCluster/staging'> </location> <location name='temp' path='/tmp'> </location> <location name='working' path='/apps/falcon/primaryCluster/working'> </location> </locations> <ACL owner='ambari-qa' group='users' permission='0x755'/> <properties> <property name='brokerImplClass' value='org.apache.activemq.ActiveMQConnectionFactory'> </property> </properties> </cluster>

I am using FalconWebUI to submit the cluster.

But if I submit the cluster with the WebUI, I should be under falcon user. Is there a way to submit with WebUI ?
