Running the JDBC Client and Viewing Results

Run the mvn package command to generate a JAR file, for example, hive-examples-1.0.jar, and obtain it from the target directory in the project directory.
Create a directory as the running directory in the running and commissioning environment, for example, /opt/hive_examples (Linux), and create the conf subdirectory in the directory.

Copy the hive-examples-1.0.jar file exported in 1 to /opt/hive_examples.

Copy the configuration file from the client to the conf directory. For a security cluster with Kerberos authentication enabled, copy the user.keytab and krb5.conf files obtained in 5 to the /opt/hive_examples/conf directory. For a cluster with Kerberos authentication disabled, you do not need to copy the user.keytab and krb5.conf files. Copy the ${HIVE_HOME}/../config/hiveclient.properties file to the /opt/hive_examples/conf directory.
```
cd /opt/hive_examples/conf
cp /opt/client/Hive/config/hiveclient.properties .
```
Prepare the JAR packages related to the sample program.

Create a directory (for example, /opt/hive_examples/lib) in the commissioning environment to store dependency JAR packages. Copy all packages in ${HIVE_HOME}/lib/ to the directory, delete the derby-10.10.2.0.jar package. (The JAR package version number varies according to the site requirements.)
```
mkdir /opt/hive_examples/lib
cp ${HIVE_HOME}/lib/* /opt/hive_examples/lib
rm -f /opt/hive_examples/lib/derby-10.10.2.0.jar
```

In Linux, run the following command to run the sample program:

chmod +x /opt/hive_examples -R 
cd /opt/hive_examples 
source /opt/client/bigdata_env
java -cp .:hive-examples-1.0.jar:/opt/hive_examples/conf:/opt/hive_examples/lib/*:/opt/client/HDFS/hadoop/lib/* com.huawei.bigdata.hive.example.ExampleMain

In the CLI, view the HiveQL query results in the example code.
If the following information is displayed, the sample project execution is successful on Linux.
```
Create table success!
_c0
0
Delete table success!
```
