当尝试在hib中对图像运行作业facecount时，我遇到了这个异常。我已经在类路径中包含了hipi-2.1.0.jar。

Exit code: 1
Stack trace: ExitCodeException exitCode=1:
at org.apache.hadoop.util.Shell.runCommand(Shell.java:576)
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，打印以下stacktrace。
