distributing execution of the first plurality of computing tasks across the computing nodes; and

testing the load on the server under test that executes the second plurality of computing requests in a production environment-by causing the first plurality of computing tasks to be executed by the computing nodes in the distributed testing environment.

2. The method of claim 1 , wherein the computing nodes include a name node and a plurality of data nodes managed by the name node.

3. The method of claim 2 , wherein distributing the execution of the first plurality of computing tasks comprises:

requesting the name node to distribute the execution of the plurality of computing tasks across the plurality of data nodes.

4. The method of claim 2 , wherein the plurality of computing requests, when executed, request responses from a first server application; and wherein the method further comprises:

detecting, using the name node, that the first server application is unresponsive; and

responsive to the detecting, automatically re-starting, using the name node, the first server application.

5. The method of claim 2 , wherein the plurality of computing requests, when executed, request responses from a first server application; and wherein the method further comprises:

detecting, using the name node, that the first server application provides a response time longer than a predefined response time; and

responsive to the detecting, automatically starting, using the name node, a second instance of the first server application.

6. The method of claim 5 , further comprising:

terminating an original instance of the first server application; and

measuring a response time of the second instance of the first server application.

7. The method of claim 6 , further comprising:

continuing the original instance of the first server application; and

determining a second response time of the first server application based on the response time of the original instance and a response time of the second instance.

8. The method of claim 1 , further comprising:

determining a performance indicator to be measured; and

generating the first plurality of computing tasks to provide a predefined number of computing requests.

9. The method of claim 1 , wherein causing the first plurality of computing tasks to be executed by the computing nodes comprises: causing the first plurality of computing tasks to be executed in a batch processing by the computing nodes.

10. The method of claim 1 , wherein the second plurality of computing requests comprises two or more types of computing tasks.

11. A system, comprising:

a non-transitory memory; and

one or more hardware processors coupled to the non-transitory memory and configured to execute instructions to perform operations comprising:

selecting a user-specified test program for execution to test a load on a server under test;

determining one or more testing parameters associated with the user-specified test program;

identifying, based on the one or more testing parameters, computing nodes within a distributed computing system used for testing a server under test;

distributing execution of the user-specified test program across the computing nodes; and

testing the load on the server under test using output generated by the user-specified test program by causing the user-specified test program to be executed by the computing nodes in the distributed computing system.

12. The system of claim 11 , wherein the operations further comprise:

measuring performance of the server under test based on execution of the user-specified test program by the computing nodes.

13. The system of claim 11 , wherein testing the server under test further comprises:

generating a predefined number of instances of the user-specified test program; and

causing the predefined number of instances of the user-specified test program to be executed by the computing nodes.

14. The system of claim 11 , wherein testing the server under test further comprises: causing the user-specified test program to be executed as part of a batch process job by the computing nodes.

15. The system of claim 11 , wherein the computing nodes include a name node and a plurality of data nodes managed by the name node.

16. The system of claim 15 , wherein distributing execution of the user-specified test program across the computing nodes comprises: requesting the name node to distribute the execution of a plurality of instances of the user-specified test program across the plurality of data nodes.

17. The system of claim 11 , wherein the distributed computing system includes a Hadoop distributed file system.

18. A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

selecting a user-specified test program for execution to test a load on a server under test;

determining one or more testing parameters associated with the user-specified test program;

identifying, based on the one or more testing parameters, computing nodes within a distributed computing system used for testing a server under test;

distributing execution of the user-specified test program across the computing nodes; and

testing the load on the server under test using output generated by the user-specified test program by causing the user-specified test program to be executed by the computing nodes in the distributed computing system.

19. The non-transitory machine-readable medium of claim 18 , wherein the computing nodes include a name node and a plurality of data nodes managed by the name node.

20. The non-transitory machine-readable medium of claim 19 , wherein distributing execution of the user-specified test program across the computing nodes comprises: requesting the name node to distribute the execution of a plurality of instances of the user-specified test program across the plurality of data nodes.
