Subject How to clean the cache when i do performance test in spark
Date Thu, 08 Dec 2016 07:47:03 GMT
Hi all:
   When I test my spark application, I found that the second round(application_1481153226569_0002)
is more faster than first round(application_1481153226569_0001).  Actually the configuration
is same. I guess the second round is improved a lot by cache. So how can I clean the cache?


Best Regards
Kelly Zhang/Zhang,Liyun
