> STEPS TO REPRODUCE:
> {code}
> CREATE TABLE `sample_07` ( `code` string , `description` string , `total_emp`
> int , `salary` int ) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED AS
> TextFile;
> load data local inpath 'sample_07.csv' into table sample_07;
> set hive.limit.pushdown.memory.usage=0.9999;
> select * from sample_07 order by salary LIMIT 999999999;
> {code}
> This will result in
> {code}
> Caused by: java.lang.OutOfMemoryError: Java heap space
> at org.apache.hadoop.hive.ql.exec.TopNHash.initialize(TopNHash.java:113)

> {code}
> The basic issue lies with top n optimization. We need a limit for the top n
> optimization. Ideally we would detect that the allocated bytes will be bigger
> than the "limit.pushdown.memory.usage" without trying to alloc it.
