我真的很难与Hadoop一起运行Hbase-MapReduce.
我确实使用Hadoop Hortonwork 2版本.我使用的HBase版本是0.96.1-hadoop2.现在,当我尝试运行我的MapReduce时：
hadoop jar target/invoice-aggregation-0.1.jar start="2014-02-01 01:00:00" end="2014-02-19 01:00:00" firstAccountId=0 lastAccountId=10
Hadoop告诉我,在其文件系统中找不到invoice-aggregation-0.1.jar？我想知道它为什么需要在那里？
这是我得到的错误

我会很感激任何建议,帮助甚至我猜我为什么会收到这个错误？
解决方法:
错误是由于hadoop无法找到放置的罐子.
放置罐子并重新运行工作.
这将解决问题.
