-----------------------------------

             Summary: The format checking of extractExecutionParams in config.sh is incorrect
                 Key: FLINK-17023
                 URL: https://issues.apache.org/jira/browse/FLINK-17023
             Project: Flink
          Issue Type: Bug
          Components: Deployment / Scripts
    Affects Versions: 1.11.0
            Reporter: Caizhi Weng


In [FLINK-15727|https://issues.apache.org/jira/browse/FLINK-15727] extractExecutionParams now returns multiple lines of results to avoid using BashJavaUtils twice. But now the format checking for the last line is incorrect. Instead of 

{code:bash}
if ! [[ $execution_config =~ ^${EXECUTION_PREFIX}.* ]]; then
        echo "[ERROR] Unexpected result: $execution_config" 1>&2
        echo "[ERROR] The last line of the BashJavaUtils outputs is expected to be the execution result, following the prefix '${EXECUTION_PREFIX}'" 1>&2
        echo "$output" 1>&2
        exit 1
    fi
{code}

It should be


{code:bash}
last_line=`echo "$execution_config" | tail -n 1`
if ! [[ "$last_line" =~ ^${EXECUTION_PREFIX}.* ]]; then
# ...
{code}
