Review comment:
Same concern here. `grep -o` can throw an error that should be caught.

> Waiting loops are broken in e2e/common.sh
> -----------------------------------------
>
> Key: FLINK-10842
> URL: https://issues.apache.org/jira/browse/FLINK-10842
> Project: Flink
> Issue Type: Bug
> Components: E2E Tests
> Affects Versions: 1.7.0
> Reporter: Andrey Zagrebin
> Assignee: Andrey Zagrebin
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.8.0
>
>
> There are 3 loops in flink-end-to-end-tests/test-scripts/common.sh where the
> script waits for some event to happen (for i in \{1..10}; do):
> - wait_dispatcher_running
> - start_and_wait_for_tm
> - wait_job_running
> All loops have 10 iterations and the loop breaks if the awaited event
> happens. If timeout occurs then the script does not fail and the function
> just continues after 10 iterations ignoring that the awaited event did not
> happen.
