Nicolas Liochon commented on HBASE-11223:
-----------------------------------------
bq. What about limit the dataLength when reading the request data from the
channel in the rpc server?
Yes, I agree.
IIRC, there is some code that does that, so may be this code comes too late and
the rs crashed already, or this code is broken...

> 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.
