> h3. *Motivation*
> A method 
> {{DistributionZonesTestUtil#deployWatchesAndUpdateMetaStorageRevision}} is 
> used in tests related to a distribution zone manager to increase a meta 
> storage applied revision before distribution manager starts. The method 
> breaks invariant: zone manager must be started before 
> metaStorageManager.deployWatches() is invoked. Need to do proper solution for 
> increasing the applied revision.
>  
> The first approach to fix it is to invoke methods in this order
>  
> {code:java}
> vaultManager.put(new ByteArray("applied_revision"), longToBytes(1)).get();
> metaStorageManager.start();
> distributionZoneManager.start();
> metaStorageManager.deployWatches();
> {code}
>  
> First we put applied_revision. Then start metaStorageManager and 
> metaStorageManager. Then deploy watches.
> The disadvantage of this method is that th ByteArray("applied_revision") is 
> an internal part of the implementation.
>  
> The second way is a restart all of the components used in the test to 
> simulate the node restart. In this case, after the zones manager's restart, 
> the revision will be greater than zero.
> h3. *Definition of Done*
> The {{deployWatchesAndUpdateMetaStorageRevision}} is replaced by proper 
> solution. Need to try approach with restart of all components.
