Description

When the client requests getScannerResults or getScannerRows, set up a large numRows will cause ArrayIndexOutOfBoundsException ，and  may  cause OOM.

For example

conn := cli.(*hbase.THBaseServiceClient)
tscan := &hbase.TScan{
   StartRow: []byte("prefix_1"),
   StopRow:  []byte("prefix_2"),
   Columns: []*hbase.TColumn{
      {
         Family:    []byte("N"),
         Qualifier: []byte("title"),
      },
   },
}
scanresult, err := conn.GetScannerResults([]byte("rowkey1"), tscan, 10000000)

Here initialize the length of resultSets using the minimum value of "hbase.thrift.max.scanner.results.init.length"  and numRows。
