-----------------------------------
Summary: Inprove HistoryServer with multithread to relay logs
Key: SPARK-11123
URL: https://issues.apache.org/jira/browse/SPARK-11123
Project: Spark
Issue Type: Improvement
Reporter: Xie Tingwen
Now,with Spark 1.4,when I restart HistoryServer,it took over 30 hours to replay
over 40 000 log file. What's more,when I have started it,it may take half an
hour to relay it and block other logs to be replayed.How about rewrite it with
multithread to accelerate replay log.
