Mark Liu commented on BEAM-1986: -------------------------------- After investigation, I have some ideas to solve it and want to discuss it here: 1. Append some random number in default job_name which is pretty straight forward. 2. I want to improve the descriptive of job_name, which can solve this problem and potentially benefit for other test runner in the further. Currently, the default pattern is "beamapp-${USER_NAME}-${DATETIME}" which is hard to tell which test is running. In Java SDK, default job_name format is more helpful: "ApplicationName-UserName-Date-RandomInteger" (https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/options/PipelineOptions.java#L261). However, Java provides ApplicationNameOptions.class to set this value and is used by constructing default job_name, but Python doesn't provide the similar options. I prefer the second solution but it involves with pipeline options design, so I want to rise ideas here and here more thoughts.
