Cannot delete an entity in Falcon

[#1]

I am getting following error on trying to delete the last entity in Falcon data pipeline

"Failed to cleanup entity path for (process) cleanseEmailProcess on cluster primaryCluster"

Understand cannot edit an entity either? https://community.hortonworks.com/questions/14631/how-to-update-falcon-cluster-entities-that-have-fe...

@Amit Tewari,

Did you bounce the falcon and su - falcon and tried the delete from the command line

falcon entity -type cluster -name <<name>> -delete

@jramakrishnan

Yes I did do su - falcon

[falcon@sandbox bin]$ ./falcon entity -type process -name rawEmailIngestProcess -delete ERROR: Bad Request;default/org.apache.falcon.FalconWebException::org.apache.falcon.FalconException: Failed to cleanup entity path for (process) rawEmailIngestProcess on cluster primaryCluster

@jramakrishnan

./falcon entity -type process -list

(PROCESS) cleanseEmailProcess

(PROCESS) rawEmailIngestProcess

./falcon entity -type process -name rawEmailIngestProcess -list

(PROCESS) cleanseEmailProcess

(PROCESS) rawEmailIngestProcess

Problem resolved.

The problem was that when I started the HDP sandbox today, somehow the namenode started in safemode (I really cant imagine why specially on a sandbox, but anyways...)

After removing the namenode from safemode, was able to remove the successfully entities.
