ASF GitHub Bot commented on FLINK-10711:
----------------------------------------

twalthr opened a new pull request #7023: [FLINK-10711] [e2e] Allow basic error 
handling with bash
URL: https://github.com/apache/flink/pull/7023
 
 
   ## What is the purpose of the change
   
   This commit modifies the test infrastructure to allow bash's basic
   error handling mechanism with `set -e`. Many tests are not
   ready for a globally defined strict error handling. For now, at
   least newly developed tests should consider this flag. If a test
   causes an error, a test fails with `"[FAIL] Test script contains errors"`.
   
   
   ## Brief change log
   
   - Make it possible to enable `set -e`
   
   
   ## Verifying this change
   
   Run `./run-single-test.sh ./test-scripts/test_batch_allround.sh` as an 
example with the `set` command uncommented.
   
   ## Does this pull request potentially affect one of the following parts:
   
     - Dependencies (does it add or upgrade a dependency): no
     - The public API, i.e., is any changed class annotated with
