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

             Summary: RotateLogFile may not work well when sed version is below 
4.2
                 Key: FLINK-8822
                 URL: https://issues.apache.org/jira/browse/FLINK-8822
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: Xin Liu
             Fix For: 1.5.0


In bin/config.sh rotateLogFilesWithPrefix(),it use extended regular to process 
filename with "sed -E",but when sed version is below 4.2,it turns out "sed: 
invalid option -- 'E'"

and RotateLogFile won't work well : There will be only one logfile no matter 
what is $MAX_LOG_FILE_NUMBER.


so use sed -r may be more suitable.
