Hi DAS teaam,
I am getting below null pointer exception while trying to execute a
scheduled task. What I simply did was created a two node HA cluster and
tried to run this example[1]. It has a scheduled task. However, this error
can not be observed in a single node fresh pack.
The error is,
[2015-12-10 19:32:00,573] INFO
