Question

当尝试在HIB中的图像上运行作业Facecount时，我收到此异常。我在课程路径中包含了hipi-2.1.0.jar。

Exit code: 1
Stack trace: ExitCodeException exitCode=1:

at org.apache.hadoop.util.Shell.run(Shell.java:487)
at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:753)

在hadoop作业日志中，打印了以下堆栈跟踪。

如何解决此问题？

Answer 1

看起来hadoop没有带你的类路径目录，你试过把hipi-2.1.0.jar放到hadoop-mapreduce / lib /文件夹中吗？

如果您使用的是cloudera，那么您必须放置库的位置，它应位于所有节点上。

的/ opt / Cloudera的/包裹/ CDH / LIB / Hadoop的映射精简/ LIB /

Hadoop map减少了hipi.mapreduce.BinaryOutputFormat未找到
