Updated on 2022-09-14 GMT+08:00
  1. 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.
  2. 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.
  3. 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.
  4. 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

  5. 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!
