hadoop - Google Compute Engine 问题上的 Spark SQL

Question

我们正在使用 bdutil 1.1 部署 Spark (1.2.0) 集群。但是，我们在启动 spark 脚本时遇到了问题:

py4j.protocol.Py4JJavaError: An error occurred while calling o70.registerTempTable.

该脚本适用于我的笔记本电脑。我在/home/hadoop/spark-install/lib 路径中有 datanucleus-api-jdo-3.2.6.jar。

有什么地方可能出错的想法吗？

Answer 1

我需要添加:

SPARK_CLASSPATH=/home/hadoop/spark-install/lib/datanucleus-api-jdo-3.2.6.jar:/home/hadoop/spark-install/lib/datanucleus-core-3.2.10.jar:/home/hadoop/spark-install/lib/datanucleus-rdbms-3.2.9.jar 

在我的 spark-submit 命令之前:

SPARK_CLASSPATH=/home/hadoop/spark-install/lib/datanucleus-api-jdo-3.2.6.jar:/home/hadoop/spark-install/lib/datanucleus-core-3.2.10.jar:/home/hadoop/spark-install/lib/datanucleus-rdbms-3.2.9.jar ../hadoop/spark-install/bin/spark-submit main.py --master spark://spark-m:7077
