Description

Develop system tests for the following cases.

1. Enable a compression emulation and generated the data using gridmix and verify whether compressed input generated or not.
2. Verify a Gridmix jobs map input, map output and reduce output compression ratios against the default compression ratios.
3. Verify a Gridmix jobs map input, map output and reduce output compression ratios against user specified compression ratios.
4. Verify a Gridmix jobs map input, map output compression ratios with file output compression format is false in original trace against default compression ratios.
5. Verify a Gridmix jobs map input, map output compression ratios with file output compression format is false in original trace against user specified compression ratios.
6. Verify a Gridmix jobs reduce output with file output compression format is true in original trace against the default compression ratios.
7. Verify a Gridmix jobs reduce output with file output compression format is true in original trace against the user specified compression ratios.
