运行 hive tpch-setup 时出错：java.lang.IllegalAccessError：类 org.apache.hadoop.hdfs.web.HftpFileSystem 无法访问其超级接口

Question

我正在尝试按照 https://github.com/hortonworks/ 的指令运行 hive tpcdh hive-testbench.git 。我遇到了以下错误。 tpcds-setup 中未出现此问题。

这不适用于 CDP Trial 7.3.1、CDH 版本：Cloudera Enterprise 6.3.4，但适用于 Apache Ambari 版本 2.6.2.2

在 hive-testbench/tpch-gen/pom.xml 中，更改了 hadoop 版本，问题得到解决

<dependencies>
  <dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-client</artifactId>
    <version>2.4.0</version>
    <scope>compile</scope>
  </dependency>
