When query elasticsearch， I use Spark sql to query elasticsearch，My Spark SQL is： “select log\_date,domain,firm\_name,sum(traffic) as traffic,concat\_ws(':',collect\_set(file\_name)) as file\_name from traff group by log\_date,domain,firm\_name”，the program can run successfully，but the sum value is not accurate，How can I get the accurate value。
