我正在MAC OSX 10.9.4中进行sqoop导入，并得到错误：

Hadoop版本：2.5.1Sqoop版本：1.4.5os:OSX10.9.4
设置env变量：
export HADOOP_COMMON_HOME=/Users/HADOOP/hadop-2.5.1/
export HADOOP_MAPRED_HOME=/Users/HADOOP/hadop-2.5.1/share/HADOOP/mapreduce/
Sqoop jar（Sqoop-1.4.5.jar）位于/Users/hadoop/hadop-2.5.1/lib中/和/Users/hadoop/scoop/lib 中的mysql连接器
中也存在core.jar
/Users/hadoop/hadoop2.5.1/share/hadoop/marepeduce/hadoop-mapreduce-client-core-2.5.1.jar
for f in ${HADOOP_MAPRED_HOME}/*.jar; do
HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:$f;
done
将其添加到bin/configure sqoop
不知何故，Jars无法访问。在将Sqoop罐子放入HDFS后，Sqoops导入顺利。此链接有帮助找不到Sqoop jar文件
cd$SQOOP_HOME/bin
vim配置sqoop
在线下添加
add_to_classpath ${HADOOP_MAPRED_HOME}
在"add_to_classpath$｛SQOOP_JAR_DIR｝"之后
尝试检查$HADOOP_COMMON_LIB_NATIVE_DIR中是否可以找到库。如果没有，你可以把它放在你的mapreduce实现的同一目录中：
/Users/hadoop/hadoop2.5.1/share/hadoop/marepeduce/
我也遇到了同样的问题！只需将hadoop-mapreduce-client-core-3.0.0-SNAPSHOT.jar从sqooq复制到lib文件夹中。脏，但它工作。您可能只是想进行一些测试
