Sample Code Error for Hive Secondary Development After Domain Switching
Symptom
In the sample code for Hive secondary development, an error "No rules applied to ****" is reported:
Cause Analysis
- The sample code for Hive secondary development loads core-site.xml file that is loaded through classload by default. Therefore, you need to put the configuration file to the classpath directory of the startup program.
- If the domain name of the cluster is changed, the core-site.xml file will change. You need to download the latest core-site.xml file and save it to the classpath directory where the sample code for Hive secondary development is located.
Solution
- Download the latest client of the Hive cluster to obtain the latest core-site.xml file.
- Save the core-site.xml file to the classpath directory where the sample code process for Hive secondary development is located.
