我正在尝试在使用 Kubernetes 部署的 zeppelin 笔记本上使用 pyspark 解释器。我已将 spark 配置为也使用 spark 执行器(5 核，1G 存储)。但是，当我尝试运行 pandas/seaborn 并操作 pandas 数据框时，出现以下错误:

我查了
/tmp/spark-local/对于每个 Spark 执行器，发现 blockmgr-aa951820-47d3-404f-a97e-12d25f460aec (如日志中所示)在 3 个 executor pod 中有 2 个不存在。我也检查了 zeppelin 服务器 pod，它没有上述预期的目录。这是我正在尝试运行的一段
%pyspark
import seaborn as sns
#Plot xxxxxxx
x = df_age.groupby("z").agg({"y":"mean"}).sort("z").toPandas()
sns.barplot("z","avg(y)", data = x, color = "cadetblue")
它有时可以工作/运行，但我希望它可以完美地工作。谢谢!

最佳答案
对于所有相关人员，我们能够验证这是一个外部 shuffle 服务问题。请检查此线程:
