Sqoop-Hive导入

我在通过sqoop将rdbms的数据导入配置单元时面临一个问题。请不要将其标记为重复Sqoop-Hive导入

我正在将数据从oracle 12c db导入到Hive中。数据是在hdfs里面创建的，但是hive表没有被创建，即一个文件夹在我导入的表的名字里面/ user/hive/warehouse里创建，但是当我进入hive编辑器并检查这个表时不显示我。

但是，如果我在导入数据（create table ..）之前创建了此表的模式，现在如果通过运行sqoop导入来导入数据，则也可以在hdfs和hive表中找到数据。

下面是我在做什么

1.正开始

usermod -a -G supergroup venkat 
    export SQOOP_HOME=/opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/sqoop 
    export HIVE_HOME=/opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/hive 
    export HADOOP_CLASSPATH=/opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/sqoop/lib/ojdbc7.jar:/opt/cloudera/parcels/CDH-5.5.1-1.cdh5.5.1.p0.11/lib/hive/lib/* 
    export HADOOP_USER_NAME=hdfs 
    export PATH=$PATH:$HIVE_HOME/bin
细节

2.运行sqoop导入

sqoop import --connect jdbc:oracle:thin:@bigdatadev2:1521/orcl --username BDD1 --password oracle123 --table EMP -m 1 --hive-import --hive-table emp

以下是日志：

4. 现在，当我创建表的架构“创建表emp ...'然后导入数据，我得到我的hdfs以及hive表中的数据。

仅当表格模式存在时才能使用sqoop吗？它不能自己创建一个新表？

我是否在我的导入命令行中丢失了某些东西。请不要将其标记为重复

但创建表脚本==> ** CREATE TABLE'emp'（'EMP_ID' STRING，'EMP_NAME' STRING）COMMENT '由sqoop上2016年4月15日十八时17分19秒进口' 行格式由'\ 001'终止的'\ 001'终结的界限字段存储为TEXTFILE **，执行时没有任何错误。只需从配置单元shell启动此命令并检查表是否已创建 –

是的，当我运行脚本CREATE TABLE emp（EMP_ID STRING，EMP_NAME STRING）时，表被创建。现在如果我运行我的sqoop导入它填充表中的数据 –

通常这些错误是由于权限错误&错误配置引起的。考虑到这不是一个增量数据摄入，下面应该工作。

我已经添加了仓库目录&配置单元覆盖选项。请在Hive &中删除现有的emp表，执行下面的命令，用hdfs中的适当仓库目录替换path/to/dir。

sqoop import --connect jdbc:oracle:thin:@bigdatadev2:1521/orcl --username BDD1 --password oracle123 --table EMP -m 1 --warehouse-dir "path/to/dir" --hive-import --hive-overwrite --hive-table emp

嗨鲁本，我运行命令，我给仓库目录/ user/hive/warehouse，因为这是我的'emp'文件夹被创建的地方（没有文件夹被创建在/ user/hdfs文件夹中）。但是仍然没有创建表 –

@HardikGupta/user/hive/warehouse是配置单元的仓库目录，通常还有sqoop的仓库目录。我的假设是，即使由于权限错误而执行“drop table emp”，表格也不会被删除。您需要小心并在整个系统中使用相同的用户以避免出现此类问题。首先，我会检查表是否被丢弃;创建＆give/user/hdfs/data作为warehouse-dir;使用hdfs用户从命令行执行sqoop命令;为emp表创建和提供特定的数据库名称。 – gkc123
