org.apache.falcon.FalconException: Failed to initialize FS for cluster : falcontest2
ROOT CAUSE: Falcon is working as expected. A fix was introduced in HDP 2.3.0 to address:
Previously, if Falcon could not access a cluster entity, it would not restart successfully. Newer versions
Verify that the cluster specified in that particular entity is accessible.
If cluster is not accessible or no longer available, remove cluster entity definition from the falcon store (default location: /hadoop/falcon/store/CLUSTER)
