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。
