Resolution: Not A Problem
> Spark SQL select query result size issue
> ----------------------------------------
>
> Key: SPARK-28707
> URL: https://issues.apache.org/jira/browse/SPARK-28707
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: jobit mathew
> Priority: Major
>
> Spark sql select * from table; query fails with the validation of
> spark.driver.maxResultSize.
> But select * from table limit 1000; pass with the same table data.
> *Test steps*
> spark.driver.maxResultSize=5120 in spark-default.conf
> 1.Create a table with more than 5KB size in my example 23KB text file with
> name consecutive2.txt
> local path /opt/jobit/consecutive2.txt
> AUS,30.33,CRICKET,1000
> AUS,30.33,CRICKET,1001

> AUS,30.33,CRICKET,1999
> 2.launch spark-sql --master yarn
> 3.create table cons5(country String,avg float, sports String, year int) row
> format delimited fields terminated by ',';
> 4.load data local inpath '/opt/jobit/consecutive2.txt' into table cons5;
> 5. select count(*)from cons5; gives 1000;
> 6.select * from cons5 *limit 1000*; query and displays the 1000 data .*Not
> getting any error and query executing successfully.*
> 7. select * from cons5;
> getting the error as mentioned below.
> *ERROR*
> select * from cons5;
> *org.apache.spark.SparkException: Job aborted due to stage failure: Total
> size of serialized results of 2 tasks (7.5 KB) is bigger than
> spark.driver.maxResultSize (5.0 KB)*
