我试图在使用Kubernetes部署的齐柏林飞艇笔记本上使用pyspark解释器。我已经将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并操纵pandas数据框时，出现以下错误：

我检查了每个/tmp/spark-local/的每个火花执行器，发现在三个执行器窗格中的两个中没有blockmgr-aa951820-47d3-404f-a97e-12d25f460aec（如日志中所示）。我也检查了Zeppelin服务器吊舱，它没有预期的上述目录。

这是我要运行的一段

%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")

它有时可以运行/运行，但我希望它可以完美运行。谢谢！

[编辑] 我在以下观察方面取得了进展：

  1. 仅存在一个spark executor pod时，所有作业都运行无错误。

  2. 关于（1），我怀疑这与火花改组有关。我正在尝试了解其工作原理，但这是我获得的最佳指导。 https://medium.com/@foundev/you-won-t-believe-how-spark-shuffling-will-probably-bite-you-also-windowing-e39d07bf754e
