This article describes how to combine ODI with Hadoop. Before doing so, make sure you have the ODI software installed and build a Hadoop environment, or you can refer to my other blog posts to build the environment.
1. Create a Directory
[[email protected] ~]# hdfs dfs -mkdir -p /user/oracle/odi_home[[email protected] ~]# hdfs dfs -chown oracle:oinstall /user/oracle/odi_home[[email protected] ~]# hdfs dfs -ls /user/oracle/drwxr-xr-x - oracle oinstall 0 2018-03-06 13:59 /user/oracle/odi_home
This directory is the root of the ODI HDFs, and if you do not create this directory, you will encounter ODI-26039 errors in subsequent steps.
2. Big Data Wizard
File->new., choose big Data configurations
3. General Settings
Prefix:前缀,默认即可。Distribution:根据CDH版本进行选择。Distribution Type:使用默认Normal即可。Base Directory:/opt/cloudera/parcels/CDHTechnologies:根据实际环境选择相关组件
The results are as follows:
4. Hadoop settings
5. HDFs Settings
6. Hive Settings
7. Oozie setting
8. Verification Settings
