Good advice!
What about limit the dataLength when reading the request data from the channel
in the rpc server?
Eg, if the dataLength is larger than 2M, just throw an exception.
> Limit the actions number of a call in the batch

> 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.
