>                 URL: https://issues.apache.org/jira/browse/MADLIB-1291
>             Project: Apache MADlib
>          Issue Type: Bug
>          Components: Module: Linear-Algebra Functions
>            Reporter: astronee jin
>            Priority: Major
>
> the bug was found by: [http://www.wotung.com|http://www.wotung.com/]   or [http://www.china-para.com|http://www.china-para.com/]
> when running the following test
> /usr/local/madlib/bin/madpack -s madlib -p hawq -c gpadmin@localhost:5432/postgres -t linalg install-check
> the programe will quit abnoramlly, 
> the case fails even by manual inputing:
>  postgres=# select madlib.dist_jaccard('\{1,-2,3}','\{4,-5,6}');
>  server closed the connection unexpectedly
>          This probably means the server terminated abnormally
>          before or while processing the request.
>  The connection to the server was lost. Attempting reset: Failed.
> after the Analysis, we think the servingp process received the abormal SIGNAL and quit, it's from abort() function. the client connection is lost too.
>  
> when debugging into function Dist.Jaccard, the memory is not released explicitly, after add the following and recomplie:
>   
> x_set.clear();
>  y_set.clear();
>   
>  we can execute the following and not abormal from the function of distJaccard：
>  postgres=# select madlib.dist_jaccard('\{1,-2,3}','\{4,-5,6}');
>   dist_jaccard 
>  --------------
>              1
