> From HBase 1.2 on, rows are not exclusively locked when the preBatchMutate call is made
(see HBASE-18474). The mutable secondary index (global and local) depend on this to get a
consistent snapshot of a row between the point when the current row value is looked up, and
when the new row is written.
