How to handle service application failures developed by Hive JDBC?

Question

I'm developing a service application based on the Hive jdbc-examples project, fail to run the application.

I normally use Huawei's big data products to perform Hive's jdbc sample development, which always fails to run the application.

Answer 1

To solve this problem, try either one of the following methods:

Method 1

Put the core-site.xml configuration file to classpath according to the Hive jdbc-examples sample project.

Method 2

In the code, explicitly load the core-site.xml file:

......conf = new Configuration(); String userdir = System.getProperty("user.dir") + File.separator + "conf" + File.separator; conf.addResource(new Path(userdir + "core-site.xml"));......

Method 3

In the code, set hadoop.security.authentication to kerberos:

......CONF = new Configuration();
CONF.set("hadoop.security.authentication", "kerberos");......
