在eclipse上,运行一个从 HBase指定table的指定行范围读取数据,经过MR后,再写到另一个table中的 MR程序,结果运行时出现:

java.io.FileNotFoundException: File does not exist: hdfs://localhost:9000/home/hadoop/CDH4Dev/hbase/lib/zookeeper-3.4.5-cdh4.5.0.jar
但是,实际上,home/hadoop/CDH4Dev/hbase/lib/zookeeper-3.4.5-cdh4.5.0.jar 是实际存在的。
并且,上述程序export成jar包后,在hadoop上shell命令,是可以执行的
无法继续下去了,请 大家指点
