sqoop2安装
1. 下载解压缩
此次安装版本为1.99.6
# Decompress Sqoop distribution tarball
tar -xvf sqoop-<version>-bin-hadoop<hadoop-version>.tar.gz
ln -s sqoop-<version>-bin-hadoop<hadoop version>.tar.gz sqoop
export SQOOP_HOME=`pwd`/sqoop
# Change working directory
cd $SQOOP_HOME
2. 配置服务
配置文件在$SQOOP_HOME/server/conf下，大多数默认配置即可。需要注意的配置是catalina.properties文件下common_loader需要正确配置hadoop库文件，包括hdfs、mapreduce、hive等所有jar包. 我的配置为:
common.loader=${catalina.base}/lib,
${catalina.base}/lib/*.jar,
${catalina.home}/lib,
${catalina.home}/lib/*.jar,
${catalina.home}/../lib/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop/lib/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop-hdfs/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop-hdfs/lib/*.jar, /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/lib/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop-yarn/*.jar,
/opt/cloudera/parcels/CDH/lib/hadoop-yarn/lib/*.jar,
/opt/cloudera/parcels/CDH/lib/hive/lib/*.jar
sqoop.properties文件的org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/etc/hadoop/conf/配置hadoop
配置文件路径，默认为/etc/hadoop/conf
3. 测试配置是否正确
运行
sqoop2-tool verify
若正确,则输出为:
Verification was successful.
Tool class org.apache.sqoop.tools.tool.VerifyTool has finished correctly
4. 下载derby 包
自带derby版本过低运行时会由于不兼容而出现以下错误：
org.apache.sqoop.common.SqoopException: JDBCREPO_0007:Unable to lease link

解决办法为下载derby最新版本，先删除/sqoop-1.99.6-bin-hadoop200/server/webapps/sqoop/WEB-INF/lib下的derby旧包，然后把新下载的derby目录下的lib下的jar包拷贝到/sqoop-1.99.6-bin-hadoop200/server/webapps/sqoop/WEB-INF/lib
5. 验证
运行bin/sqoop2-shell,进入sqoop shell模式, 运行show version --all，若能正确输出server版本，则安装成功:
sqoop:000> show version --all
