我正在运行我的模型训练，每当我将maxDepth增加到12时，我就会收到StackOverflow错误。 一切正常5,10,11。
我正在使用spark 2.0.2（我无法在接下来的几周内升级它）。 我有＆gt; 3M数据，200个特征，2500棵树，我想通过增加最大深度来提高准确性。有办法克服这个问题吗？

答案 0 :(得分：2)
看起来像指定spark-submit选项：
--conf spark.executor.extraJavaOptions=-Xss8m --conf spark.driver.extraJavaOptions=-Xss8m
完成这项工作。
这也可以在每个节点的conf / spark-env.sh中配置，更多关于： http://spark.apache.org/docs/latest/configuration.html
