Question

Spark版本1.6.2 Hadoop版本2.7.3

在独立群集模式下运行spark时

命令wordcount示例：

spark-submit --class org.apache.spark.examples.JavaWordCount --master spark://IP:7077 spark-examples-1.6.2.2.5.0.0-1245-hadoop2.7.3.2.5.0.0-1245.jar file.txt output

获得以下错误

似乎Failed to create directory /usr/hdp/2.5.0.0-1245/spark/work是根本原因。在获得/usr/hdp/2.5.0.0-1245/spark/work路径的许可后，它运行良好

运行spark wordcount示例时出现IllegalStateException
