在hadoop的集群中运行sqoop时报错如下：
16/04/28 06:21:41 ERROR : Encountered IOException running import job:

错误中可以看到有这么语句话
hdfs://mycluster/home/sqoop-1.4.6/lib/commons-codec-1. 红色部分“hdfs://mycluster” 说明查找commons-codec-1. 是在hadoop集群中查找，同时jar包是个资源是由resourcemanager统一管理，如此推测很有可能是中配置不正确所导致。
解决办法如下：
1.修改hadoop配置目录中的的内容如下：红色部分需根据自己的集群配置情况而定
<configuration>
<property>
<name>-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name></name>
<value>true</value>
</property>
<property>
<name>-id</name>
<value><span style="color:#ff0000;">mycluste</span>r</value>
</property>
<property>
<name>-ids</name>
<value>rm1,rm2</value>
</property>
<property>
<name>.rm1</name>
<value><span style="color:#ff0000;">node5</span></value>
</property>
<property>
<name>.rm2</name>
<value><span style="color:#ff0000;">node8</span></value>
</property>
<property>
<name>-address</name>
<value><span style="color:#ff0000;">node5,node6,node7</span></value>
</property>
</configuration>
2.修改内容如下：
<configuration>
<property>
<name></name>
<value>yarn</value>
</property>
</configuration>
修改完以上两个文件的内容后重新启动hadoop集群和运行sqoop命令即可，
