我安装了单节点 HDFS 和本地模式 Apache Hama 0.7.1,安装似乎成功了。

但我无法通过运行提供的任何示例来测试它,比如运行 PiEstimator:

$ $HAMA_HOME/bin/hama jar hama-examples-0.7.1.jar pi
18/04/04 01:47:06 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

除了这个警告,它不会在终端上输出任何东西,也不会在$HAMA_HOME/logs目录中输出任何东西,并且永远等到我按下Ctrl+ C。互联网上的大多数文章都没有解决这个问题,它似乎适用于所有人。

如果以下内容相关,请粘贴此内容(我对这一切都很陌生):

$ hdfs dfsadmin -report
