Cannot delete an entity in Falcon

amittewari_5 — Thu, 31 Mar 2016 17:13:22 GMT

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"

PS- Followed instructions verbatim on: http://hortonworks.com/hadoop-tutorial/defining-processing-data-end-end-data-pipeline-apache-falcon

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

@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

./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.
