Commissioning Applications on Linux

Create a directory as the running directory in the running and commissioning environment, for example, /opt/impala_examples, and create the conf subdirectory in the directory.
Run the mvn package command to obtain a JAR package, for example, impala-examples-mrs-2.1-jar-with-dependencies.jar obtained from the target directory of the project and copy the package to the /opt/impala_examples directory.
For a security cluster with Kerberos authentication enabled, copy the user.keytab and krb5.conf files obtained in Preparing a Developer Account to the /opt/impala_examples/conf directory.
In Linux, run the following command to run the sample program:

chmod +x /opt/impala_examples -R

cd /opt/impala_examples

java -cp impala-examples-mrs-2.1-jar-with-dependencies.jar com.huawei.bigdata.impala.example.ExampleMain
In the CLI, view the Impala SQL 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!
```
