Chesnay Schepler created FLINK-18217:
----------------------------------------
Summary: config.sh#extractExecutionResults does not fail on empty
input
Key: FLINK-18217
URL: https://issues.apache.org/jira/browse/FLINK-18217
Project: Flink
Issue Type: Bug
Reporter: Chesnay Schepler
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.
