Hadoop版本：2.5.1 Sqoop版本：1.4.5 os：OSX10.9.4

设置了env varibles：

export HADOOP_COMMON_HOME = / Users / hadoop / hadoop-2.5.1 /

导出HADOOP_MAPRED_HOME = / Users / hadoop / hadoop-2.5.1 / share / hadoop / mapreduce /

Sqoop jar（sqoop-1.4.5.jar）放在/Users/hadoop/hadoop-2.5.1/lib/   和/ Users / hadoop / sqoop / lib
中的mysql连接器

核心.jar也存在于

中

/Users/hadoop/hadoop-2.5.1/share/hadoop/mapreduce/hadoop-mapreduce-client-core-2.5.1.jar

Answer 1

for f in ${HADOOP_MAPRED_HOME}/*.jar; do
HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:$f;
done

将其添加到bin / configure-sqoop

Answer 2

不知怎的，罐子无法进入。将Sqoop罐放入HDFS后，Sqoop进口顺利。这个链接有帮助 Sqoop jar files not found

Answer 3

尝试检查您的$ HADOOP_COMMON_LIB_NATIVE_DIR中是否可以找到该库。如果没有，你可以将它放在mapreduce实现的同一个目录中：

/Users/hadoop/hadoop-2.5.1/share/hadoop/mapreduce /

Answer 4

我遇到了同样的问题！只需将hadoop-mapreduce-client-core-3.0.0-SNAPSHOT.jar从sqooq复制到lib文件夹中。很脏，但它的工作原理。你可能只是想做一些测试

Answer 5

cd $ SQOOP_HOME / bin

vim configure-sqoop

添加以下行

add_to_classpath ${HADOOP_MAPRED_HOME}

在“add_to_classpath $ {SQOOP_JAR_DIR}”

之后

引起：java.lang.ClassNotFoundException：org.apache.hadoop.mapreduce.InputFormat
