[CONTROLLER-813] Clustering : Transaction not created as Leader is not found

Tue, 16 Sep 2014 23:46:34 +0000

I had given the shard name as car-person instead of car-people (which was there in the namespace) – In this case the sharding strategy should have defaulted to default shard but in my cluster scenario – I got the following exception
—
Caused by: java.lang.IllegalStateException: Could not find leader so transaction cannot be created

i.e. leader could not be determined when I did some REST Conf operations on car-people module..

errors: [error-type: application, error-tag: operation-failed, error-message: Problem to get data from transaction.error-info: ReadFailedException
