> Enabling ACIDv1 on a cluster produces a central locking bottleneck for all 
> table types, which is not always the intention.
> The Hive locking for non-acid tables are advisory (i.e a client can 
> write/read without locking), which means that the implementation does not 
> offer strong consistency despite the lock manager consuming resources 
> centrally.
> Disabling this lock acquisition would improve the performance of non-ACID 
> tables co-existing with a globally configured DbTxnManager implementation.
