> Key: FLINK-18217
> URL: https://issues.apache.org/jira/browse/FLINK-18217
> Project: Flink
> Issue Type: Bug
> Reporter: Chesnay Schepler
> Priority: Blocker
>
> If the BashJavaUtils fail, and {{config.sh#extractExecutionResults}} is
> called with the exception output, which does not contain the expected lines,
> then it will not detect an error.
> {code}
> execution_results=$(echo "${output}" | grep ${EXECUTION_PREFIX})
> num_lines=$(echo "${execution_results}" | wc -l)
> if [[ ${num_lines} -ne ${expected_lines} ]]; then
> {code}
> Apparently, even if {{execution_results}} is empty, {{$(echo
> "${execution_results}" | wc -l)}} returns 1.
