a2l007 opened a new issue #8494: Fix batch index task naming convention to accommodate simultaneous tasks URL: https://github.com/apache/incubator-druid/issues/8494 ### Description Modify the batch indexing task ID generation logic from `<index_type_name>_<datasource>_timestamp` to `<index_type_name>_<random_id>_<datasource>_timestamp` This would impact native index tasks as well as hadoop index tasks. ### Motivation With the existing task naming convention, if there are multiple indexing tasks submitted at the same time for a datasource, only one of the tasks gets accepted and the remaining tasks fail with `Task[xxx] already exists`. I'd like to modify the naming convention to the one mentioned above, so that this issue can be avoided. @jihoonson Any comments regarding this?
