java - Hadoop map reduce hipi.mapreduce.BinaryOutputFormat 未找到

Question

尝试对 HIB 中的图像运行 Facecount 作业时，出现此异常。我在类路径中包含了 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。

如何解决这个问题？

Answer 1

看起来 hadoop 没有带您的类路径目录，您是否尝试将 hipi-2.1.0.jar 放入 hadoop-mapreduce/lib/文件夹中？

如果您使用的是 cloudera，这是您必须放置库的位置，它应该在所有节点上。

/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/lib/
