-------------------------------------

> In HBase 1.3, it turns out that rows are not exclusively locked when the
> preBatchMutate call is made. The mutable secondary index (global and local)
> depend on this to get a consistent snapshot of a row. This will likely get
> fixed in HBASE-18474, but we need to guard against this ourselves.
