Greetings,
I have a three-node Cellar cluster.
I am on node1 and ran this command
cluster:bundle-update default XXX
The command ran successfully
As I try to subsequently run any cluster:bundle-* command (e.g.
cluster:bundle-list default) I get a java.lang.NullPointerException and the
following in the log on every node:

The problem only goes away once all nodes are fully restarted.
I would appreciate an insight into the problem!
Thank you,
Oleg
