• 【sqoop】安装配置测试sqoop1


    3.1.1 下载sqoop1:
    sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz

    3.1.2 解压并查看目录:

    [hadoop@hadoop01 ~]$ tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz --解压
    [hadoop@hadoop01 ~]$ cd sqoop-1.4.7.bin__hadoop-2.6.0
    [hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ ls -ll -查看目录

    3.2 配置sqoop——mysql连接器:
    下载mysql-connector-java-8.0.16.jar,并将其拷贝至sqoop安装目录下的lib文件夹里

    3.3 配置sqoop环境变量:

    [hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ cd conf
    [hadoop@hadoop01 conf]$ ls -ll
    total 28
    -rw-rw-r--. 1 hadoop hadoop 3895 Dec 19  2017 oraoop-site-template.xml
    -rw-rw-r--. 1 hadoop hadoop 1404 Dec 19  2017 sqoop-env-template.cmd
    -rwxr-xr-x. 1 hadoop hadoop 1345 Dec 19  2017 sqoop-env-template.sh
    -rw-rw-r--. 1 hadoop hadoop 6044 Dec 19  2017 sqoop-site-template.xml
    -rw-rw-r--. 1 hadoop hadoop 6044 Dec 19  2017 sqoop-site.xml


    3.3.1 拷贝复制sqoop-env.sh样本,并添加hadoop、hbase、hive、zookeeper的安装目录(注:没有的就不添加)

    [hadoop@hadoop01 conf]$ cp sqoop-env-template.sh sqoop-env.sh
    [hadoop@hadoop01 conf]$ gedit sqoop-env.sh
    修改的内容:
    #Set path to where bin/hadoop is available
    export HADOOP_COMMON_HOME=/home/hadoop/hadoop-3.2.0
    
    #Set path to where hadoop-*-core.jar is available
    export HADOOP_MAPRED_HOME=/home/hadoop/hadoop-3.2.0
    
    #set the path to where bin/hbase is available
    export HBASE_HOME=/home/hadoop/hbase-2.2.1
    
    #Set the path to where bin/hive is available
    export HIVE_HOME=/home/hadoop/apache-hive-3.1.2-bin
    
    #Set the path for where zookeper config dir is
    export ZOOCFGDIR=/home/hadoop/apache-zookeeper-3.5.5


    3.3.2 配置linux环境变量

    [hadoop@hadoop01 conf]$ gedit ~/.bash_profile
    [hadoop@hadoop01 conf]$ source ~/.bash_profile
    新添加:
    #sqoop
    export SQOOP_HOME=/home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0
    export PATH=$PATH:$SQOOP_HOME/bin


    3.4 验证sqoop是否安装成功

    [hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ bin/sqoop help --执行该命令,看到如下信息就表示成功
    Warning: /home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0/../hcatalog does not exist! HCatalog jobs will fail.
    Please set $HCAT_HOME to the root of your HCatalog installation.
    Warning: /home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0/../accumulo does not exist! Accumulo imports will fail.
    Please set $ACCUMULO_HOME to the root of your Accumulo installation.
    Warning: /home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0/../zookeeper does not exist! Accumulo imports will fail.
    Please set $ZOOKEEPER_HOME to the root of your Zookeeper installation.
    Error: Could not find or load main class org.apache.hadoop.hbase.util.GetJavaProperty

    3.5 测试sqoop与mysql的连接
    sqoop list-tables --username User --password 'User_123456' --connect jdbc:mysql://localhost:3306/hahive /**方式1**/
    sqoop list-tables --username User -P --connect jdbc:mysql://localhost:3306/hahive  /**方式2**/
    Enter password:

    如果能执行以上操作,可以看见结果,说明sqoop能连接mysql。
