Description

Batch validation and preparation can be done before we start iterating over batch operations for writes. observedExceptions, familyCellMaps and durability can be stored in BatchOperation as they are batch wide. For all operations, done by preBatchMutate() CP hook, operation status needs to be SUCCESS. Modify and use doWALAppend() from doMiniBatchMutate().
