Robert Nettleton commented on AMBARI-6957:
------------------------------------------
I think this problem may be related to the recent changes in the Cluster
resource provider.
In the latest Blueprint code, if one of a certain set of services is not
enabled (examples: Falcon, Oozie, Hive), then a NullPointerException will occur
that is similar to the stack trace listed in the bug that Sid just filed.
I’m currently working on a fix for this, but in the meantime you can probably
work around this by adding one of the missing services, even if these services
are not required by your cluster. In particular, you might want to try adding
the “FALCON_SERVER” to one of your host groups, which will force the Falcon
config to be pulled in, and thus avoid the NullPointer until I have the fix
ready to submit as a patch.
