Hi Xi Shen The warning message wasn’t removed after I had upgraded my java to V8, but anyway I appreciate your kind help.
Since it’s just a WARN, I suppose I can bear with it and nothing bad would really happen. Am I right? 6/10/18 11:12:42 WARN RandomForest: Tree learning is using approximately 268437864 bytes per iteration, which exceeds requested limit maxMemoryUsage=268435456.

Hi Xi Shen Not yet. For the moment my idk for spark is still V7. Thanks for your reminding, I will try it out by upgrading java. 发件人: Xi Shen <davidshe...@gmail.com<mailto:davidshe...@gmail.com>> 日期: 2016年10月17日 星期一 下午8:00 至: zhangjianxin <zhangjian...@didichuxing.com<mailto:zhangjian...@didichuxing.com>>, "user@spark.apache.org<mailto:user@spark.apache.org>" <user@spark.apache.org<mailto:user@spark.apache.org>> 主题: Re: Did anybody come across this random-forest issue with spark 2.0.1.

The same training data and same source code work in 1.6.1, however become lousy in 2.0.1 [cid:BD0EFC31-F4CE-421F-BC94-79EF3BE09D60] -- Thanks, David S.
