在R中拟合Spark ML逻辑回归时的ArrayIndexOutOfBoundsException

我正在尝试使用 sparklyr::ml_logistic_regression 来拟合逻辑回归模型 . 我的训练数据集包含42,457行和785列;响应是 label 列中的0/1整数，所有剩余列都是0/1整数特征 . 我的源数据位于R数据框（ df ）中，我可以使用 glm(label ~ ., data = df, family = binomial) 在基础R中成功地拟合模型 .

不幸的是我无法使用 ml_logistic_regression 来适应这个模型 . 代码如下; sc 是现有的Spark连接 .

library(sparklyr)
library(tidyverse)

copy_to(sc, df, "spark_train", overwrite = TRUE)
train_tbl <- tbl(sc, "spark_train")
fit <- ml_logistic_regression(train_tbl, label ~ .)

这是一个堆栈跟踪：

d> fit <- ml_logistic_regression(train_tbl, label ~ .)
* No rows dropped by 'na.omit' call
