> The current implementation of 'creating intermediate streams' depends on 
> leader election, followed by the leader creating the intermediate streams. We 
> have removed this dependency on leader election and changed the Latch 
> interface to a generic Lock interface. Following this, any processor that 
> acquires the lock can create the intermediate streams, irrespective of 
> whether it is the leader or not. It releases the lock after successful 
> creation of the streams.
