zhoukang updated SPARK-20582:
-----------------------------
Description:
In the current code of HistoryServer,jetty server will be started after
all the logs fetch from yarn has been replayed.However,when the number of logs
is becoming larger,the start time of jetty will be too long.
Here,we implement a solution which using ApplicationAttemptInfo
checkpointing to speed up the start of historyserver.When historyserver is
starting,it will load ApplicationAttemptInfo from checkpoint file first if
exists which is faster then replaying one by one.
