wonook opened a new pull request #94: [NEMO-152] Multiple physical plans execution URL: https://github.com/apache/incubator-nemo/pull/94 JIRA: [NEMO-152: Multiple physical plans execution](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-152) **Major changes:** - Divides the usage of the word 'Job' and 'Plan' to be more specific about what is being run. Before, a job had a single physical plan, so it was possible to use them with an identical name, but as jobs can contain multiple physical plans, it was necessary to divide them - Fixes the scheduler and the scheduler runner to accept multiple physical plans **Minor changes to note:** - Grammatical errors on the comments - The convert method on the DAG had almost no usages, and it was misleading on the way it was used, so it was removed. - I've allowed multiple spark contexts on an evaluator, so that an evaluator can be reused for multiple physical plans. **Tests for the changes:** - A sample program, performing a line count on one execution, and then word count on another, is added as an integration test. All existing tests pass with the changes. **Other comments:** - N/A resolves [NEMO-152](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-152)
