[SPARK-5522] Accelerate the Histroty Server start
When starting the history server, all the log files will be fetched and
parsed in order to get the applications' meta data e.g. App Name, Start Time,
Duration, etc. In our production cluster, there exist 2600 log files (160G) in
HDFS and it costs 3 hours to restart the history server, which is a little bit
too long for us.
It would be better, if the history server can show logs with missing
information during start-up and fill the missing information after fetching and
parsing a log file.
