             Summary: Jetty property handling
                 Key: SPARK-28861
                 URL: https://issues.apache.org/jira/browse/SPARK-28861
             Project: Spark
          Issue Type: Wish
          Components: Spark Submit
    Affects Versions: 2.4.3
            Reporter: Ketan


While processing data from certain files a NumberFormatExceltion was seen in the logs. The processing was fine but the following stacktrace was observed:

{"time":"2019-08-16 08:21:36,733","level":"DEBUG","class":"o.s.j.u.Jetty","message":"","thread":"Driver","appName":"app-name","appVersion":"APPLICATION_VERSION","type":"APPLICATION","errorCode":"ERROR_CODE","errorId":""}
java.lang.NumberFormatException: For input string: "unknown".

On investigation it is found that in the class Jetty there is the following:

BUILD_TIMESTAMP = formatTimestamp(__buildProperties.getProperty("timestamp", "unknown")); 

which indicates that the config should have the 'timestamp' property. If the property is not there then the default value is set as 'unknown' and this value causes the stacktrace to show up in the logs in our application. It has no detrimental effect on the application as such but could be addressed.
