我使用的是hadoop2.9.1和github的最新hipi。它运行在带有openjdk 10的ubuntu18.04.3上。
安装成功了，我试着从hipi运行这个示例。下载了一组图像后，我试图将其转换为hipiimagebundle。结果如下：

hadoop@master:~/workspace/hipi$ tools/hibImport.sh ~/workspace/SampleImages ~/workspace/SampleImages/sampleimages.hib
Input image directory: /home/hadoop/workspace/SampleImages
Input FS: local FS
Output HIB: /home/hadoop/workspace/SampleImages/sampleimages.hib
Overwrite HIB if it exists: false

问题解决了。hipi中有一个bug。
在tools/build.gradle中，注解了错误的一行：

hadoop@master:/opt/hipi/tools$ cat build.gradle 
subprojects {

  dependencies {
    compile project(':core')
  }

  jar {
    manifest {
      # Uncomment this line
      attributes("Class-Path" : configurations.runtime.collect { it.getAbsolutePath() }.join(' '));
      # Comment this line out
  //    attributes("Class-Path" : configurations.runtime.collect { it.toURI() }.join(' '));
    }
  }
}

第二个问题是图像损坏的问题。当你加载它们时，你会得到一个nullpointerexception。
