Description

Noticed additional double quotes in select * <complex datatypes> output while running it through HiveServer2/Beeline

Actual

[18,19]	"{""col1"":""alice brown"",""col2"":18}"	"{""alice brown"":18}"
[18,19]	"{""col1"":""alice garcia"",""col2"":18}"	"{""alice garcia"":18}"
[18,19]	"{""col1"":""alice garcia"",""col2"":18}"	"{""alice garcia"":18}"
[18,19]	"{""col1"":""alice thompson"",""col2"":18}"	"{""alice thompson"":18}"
[18,19]	"{""col1"":""alice xylophone"",""col2"":18}"	"{""alice xylophone"":18}"
[18,19]	"{""col1"":""bob hernandez"",""col2"":18}"	"{""bob hernandez"":18}"
[18,19]	"{""col1"":""bob ichabod"",""col2"":18}"	"{""bob ichabod"":18}"

Expected

[18,19]	{"col1":"alice brown","col2":18}	{"alice brown":18}
[18,19]	{"col1":"alice garcia","col2":18}	{"alice garcia":18}
[18,19]	{"col1":"alice garcia","col2":18}	{"alice garcia":18}
[18,19]	{"col1":"alice thompson","col2":18}	{"alice thompson":18}
[18,19]	{"col1":"alice xylophone","col2":18}	{"alice xylophone":18}
[18,19]	{"col1":"bob hernandez","col2":18}	{"bob hernandez":18}
[18,19]	{"col1":"bob ichabod","col2":18}	{"bob ichabod":18}

Run these queries through HiveServer2 to reproduce the issue:

create table insert_9 (a array<int>, b struct<col1:string,col2:int>, c map<string, int>);
 insert overwrite table insert_9 select array(age, age+1), struct(name, age), map(name, age) from studenttab10k;
select * from insert_9;
