@Override
public WriteEntry writeMiniBatchOperationsToMemStore(
final MiniBatchOperationInProgress<Mutation> miniBatchOp, @Nullable
WriteEntry writeEntry)

if (writeEntry == null) {
writeEntry = region.mvcc.begin();
}

super.writeMiniBatchOperationsToMemStore throw a exception and the new
writeEntry cannot be complete and make the MVCC stuck.
