У меня есть список строк в Python.Я создал из него блок данных с одним столбцом с таким кодом:
skills_df = spark.createDataFrame(temp, StringType())
, где temp - список строк.Этот шаг был успешно выполнен.
Когда я пытаюсь выполнить какое-либо действие на skills_df
, например skills_df.count()
, оно выдает ошибку.Это происходит с этим фреймом данных.Но не с фреймом данных, который я создал, импортируя CSV-файл, то есть csv_df = spark.read.csv('/user/turing/Profiles_final.csv', header=True)
.Я запустил это, используя spark-submit
.Хотя для отладки я запустил тот же код в pyspark
, я получил ту же ошибку.Но когда я сделал csv_df.count()
, даже после того, как произошла ошибка, она работала нормально.Пожалуйста, помогите мне с этой ошибкой.Ниже приведена трассировка стека:
