> Huge batch operation will make regionserver crash for GC.
> The extreme code like this:
> {code}
>     final List<Delete> deletes = new ArrayList<Delete>();
>     final long rows = 4000000;
>     for (long i = 0; i < rows; ++i) {
>       deletes.add(new Delete(Bytes.toBytes(i)));
>     }
>     table.delete(deletes);
> {code}
> We should limit the actions number of a call in the batch.
