hadoop - hbase mapreduce文件未找到异常

Question

我已经在2台机器上安装了hadoop 2.4.1和hbase 0.98.8。当我运行hbase mapreduce作业时，出现以下错误:

Exception in thread "main" java.io.FileNotFoundException: File does not exist: hdfs://pc1/opt/hbase-0.98.8-hadoop2/lib/hbase-server-0.98.8-hadoop2.jar

我可以运行hadoop mapreduce作业和简单的hbase作业，而不会出现任何问题。我尝试运行的代码就是应该运行的示例。

Answer 1

请提供“jps”输出。
因为您的hbase似乎无法正常工作，所以希望问题出在Zookeeper上
