Configuring the Python Sample Project

Scenario

To run the Python interface example codes of the Hive component of MRS, perform the following operations.

Procedure

  1. Python of 2.6.6 or a higher version has been installed on a client. The Python version cannot be higher than 2.7.13.

    The Python version can be viewed by running the python command on the command-line interface (CLI) of the client. The following information indicates that the Python version is 2.6.6. 
       Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48)  
   [GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2 
   Type "help", "copyright", "credits" or "license" for more information.

  2. Setuptools of 5.0 or a higher version has been installed on a client. The setuptools version cannot be higher than 36.8.0.

    To obtain the software, visit the official website.

    https://pypi.org/project/setuptools/#files

    Copy the downloaded setuptools package to the client, decompress the package, go to the decompressed directory, and run the python setup.py install command in the CLI of the client.

    The following information indicates that setuptools 5.7 is installed successfully.

      Finished processing dependencies for setuptools==5.7

  3. Install Python on the client.

    1. Obtain the sample project folder python-examples in the src\hive-examples directory where the sample code is decompressed. For details, see Obtaining Sample Projects from Huawei Mirrors.
    2. Go to the python-examples folder.
    3. Go to the python-examples folder.
    4. Run the python setup.py install command in the CLI.

      The following information indicates that Python is installed successfully.

         Finished processing dependencies for pyhs2==0.5.0

  4. After the installation is successful, the following files are generated. python-examples/pyCLI_sec.py is the Python client example codes. python-examples/pyhs2/haconnection.py is the Python client API. Run hive_python_client scripts to execute the SQL functions, for example, hive_python_client 'show tables'.

    This function applies to only simple SQL statements and depends on the ZooKeeper client.
